SVG generation via DAX measures and extension measures with ImageUrl data category for inline visualizations in PBIR reports. Automatically invoke when the user mentions "SVG visual", "DAX sparkline", "SVG measure", "inline graphics with DAX", "ImageUrl data category", "extension measure", or asks to create any DAX-generated chart (progress bars, bullet charts, KPI indicators, data bars, gauges, donut charts, lollipop charts, dumbbell charts, status pills, overlapping bars, boxplots, IBCS bars, jitter plots, box-and-whisker charts).

SVG Visuals via DAX Measures (PBIR)

Use pbir for every report mutation. The pbir-format skill is read-only schema context. If the CLI is unavailable or lacks an operation, stop and report the gap.

Generate inline SVG graphics using DAX measures that return SVG markup strings. These render as images in table, matrix, card, image, and slicer visuals. Store as extension measures in reportExtensions.json.

How It Works

  1. A DAX measure returns an SVG string prefixed with data:image/svg+xml;utf8,
  2. The measure's dataCategory is set to ImageUrl
  3. Power BI renders the SVG as an image in supported visuals

Supported Visuals

  • Table (tableEx): grid.imageHeight / grid.imageWidth -- references/svg-table-matrix.md
  • Matrix (pivotTable): same as table -- references/svg-table-matrix.md
  • Image (image): sourceType='imageData' + sourceField -- references/svg-image-visual.md
  • Card/New (cardVisual): callout.imageFX -- references/svg-card-slicer.md
  • Slicer/New (advancedSlicerVisual): header images -- references/svg-card-slicer.md

Workflow: Creating an SVG Measure

Step 0: Design and Preview

Before writing DAX, design the SVG visually:

  1. Query the model first -- use DAX Studio or Tabular Editor CLI to get actual values with the intended filter context. Use real numbers, not placeholders.
  2. Write static SVG to a temp file -- save to /tmp/mockup.svg and open it in a browser to preview layout, colors, and proportions.
  3. Ask for feedback before converting to DAX -- iterating on static SVG is far easier than on DAX string concatenation.
  4. Colors must be hex codes with # -- e.g., fill='#2B7A78'. Never use %23 URL encoding or named colors. Always hex.
Step 1: Create the Extension Measure

Create the extension measure in reportExtensions.json manually (see the pbir-format skill in the pbip plugin for JSON structure).

# Example using pbir_object_model (if available):
report.add_extension_measure(
    table="Orders",
    name="Sparkline SVG",
    expression='''
        VAR _Prefix = "data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 100 30'>"
        VAR _Bar = "<rect x='0' y='0' width='50' height='30' fill='#2196F3'/>"
        VAR _Suffix = "</svg>"
        RETURN _Prefix & _Bar & _Suffix
    ''',
    data_type="Text",
    data_category="ImageUrl",
    display_folder="SVG Charts",
)
report.save()
Step 1b: Review

Before presenting the measure to the user, dispatch the svg-reviewer agent to validate syntax and provide design feedback.

Step 2: Bind to a Visual

Extension measures use "Schema": "extension" in the SourceRef:

{
  "field": {
    "Measure": {
      "Expression": {
        "SourceRef": {"Schema": "extension", "Entity": "Orders"}
      },
      "Property": "Sparkline SVG"
    }
  }
}

For image visuals, bind the SVG measure through pbir add visual image --image; see references/svg-image-visual.md.

Step 3: Validate

Validate with pbir validate "Report.Report" --all and inspect bindings with pbir visuals bind "...Visual" --show.

Prefer UDF Libraries Over Custom DAX

Before writing a custom SVG measure from scratch, check whether an existing UDF library already provides the chart type:

To check if a library is installed, look for functions/measures starting with PowerofBI.IBCS., Viz., Compound., or Element.. Only write custom SVG DAX when no library function covers the required visualization. See references/community-examples.md for full function listings and additional libraries.

Installing UDF libraries

UDF libraries are installed into the semantic model, not the report. Use one of these tools:

  • Tabular Editor CLI (te command) -- use the te-docs skill for guidance
  • Power BI MCP server -- if available, use it to modify the model directly
  • connect-pbid skill -- connect to Power BI Desktop's local Analysis Services instance via TOM/PowerShell
  • tmdl skill -- edit TMDL files directly in a PBIP project (last resort)

DAX SVG Conventions

Measure Structure (VAR Pattern)

Every SVG measure must follow a strict VAR-based structure. Organize code into clearly separated regions:

SVG Measure =
-- CONFIG: Input fields and visual parameters
VAR _Actual = [Sales Amount]
VAR _Target = [Sales Target]
VAR _Scope = ALLSELECTED ( 'Product'[Category] )

-- CONFIG: Colors
VAR _BarColor = "#5B8DBE"
VAR _TargetColor = "#333333"

-- NORMALIZATION: Scale values to SVG coordinate space
VAR _AxisMax = CALCULATE( MAXX( _Scope, [Sales Amount] ), REMOVEFILTERS( 'Product'[Category] ) ) * 1.1
VAR _AxisRange = 100
VAR _ActualNormalized = DIVIDE( _Actual, _AxisMax ) * _AxisRange

-- SVG ELEMENTS: One VAR per visual element
VAR _SvgPrefix = "data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 100 25'>"
VAR _Sort = "<desc>" & FORMAT( _Actual, "000000000000" ) & "</desc>"
VAR _Bar = "<rect x='0' y='5' width='" & _ActualNormalized & "' height='15' fill='" & _BarColor & "'/>"
VAR _TargetLine = "<rect x='" & DIVIDE( _Target, _AxisMax ) * _AxisRange & "' y='2' width='2' height='21' fill='" & _TargetColor & "'/>"
VAR _SvgSuffix = "</svg>"

-- ASSEMBLY: Combine in rendering order (back to front)
VAR _SVG = _SvgPrefix & _Sort & _Bar & _TargetLine & _SvgSuffix

RETURN _SVG

Key conventions:

  • CONFIG section first -- input measures, scope column, colors, font settings. Users change only this section.
  • NORMALIZATION section -- scale raw values to SVG coordinate space (see below)
  • SVG ELEMENTS -- one VAR per <rect>, <circle>, <text>, <line>, etc.
  • ASSEMBLY -- concatenate elements in document order (first = back layer, last = front)
  • <desc> sort trick -- embed FORMAT(_Actual, "000000000000") in a <desc> tag so the table/matrix can sort by the SVG column
Axis Normalization (Critical)

SVG coordinates must be normalized to a fixed range. Raw measure values (e.g., 1,234,567) cannot be used directly as pixel coordinates. The standard pattern:

-- 1. Define the SVG coordinate range
VAR _BarMin = 0       -- leftmost position (or offset for labels)
VAR _BarMax = 100     -- rightmost position

-- 2. Find the maximum value across all rows in the visual's filter context
VAR _Scope = ALLSELECTED( 'Table'[GroupColumn] )
VAR _MaxInScope = CALCULATE( MAXX( _Scope, [Measure] ), REMOVEFILTERS( 'Table'[GroupColumn] ) )
VAR _AxisMax = _MaxInScope * 1.1   -- 10% padding

-- 3. Normalize each value to the SVG range
VAR _AxisRange = _BarMax - _BarMin
VAR _Normalized = DIVIDE( _Actual, _AxisMax ) * _AxisRange

Use ALLSELECTED for the scope when the chart should respond to slicer context. Use ALL for a fixed axis across all filter contexts. The * 1.1 padding prevents bars from touching the edge.

HASONEVALUE Guard

Table/matrix SVG measures must guard against subtotal/total rows where multiple categories are in scope:

IF( HASONEVALUE( 'Table'[GroupColumn] ),
    -- SVG code here
)

Without this guard, the measure evaluates on grand total rows with meaningless aggregated values.

Escaping and Color Rules
  • Single quotes for SVG attributes -- avoids DAX double-quote escaping: fill='#2196F3'
  • Double quotes in DAX: escape as "" (DAX convention)
  • viewBox for responsive scaling: viewBox='0 0 100 25'
  • xmlns required on <svg> element
  • Hex colors with # only -- e.g., fill='#2196F3'. %23 URL encoding causes errors in image visuals. Never use named colors.
  • No JavaScript -- SVG must be purely declarative
SVG Coordinate System
  • Y=0 is at the top -- invert values for charts: _Height - _Value
  • Use viewBox with a 0-100 range for normalized coordinates
  • Elements render in document order (first = back, last = front)
CONCATENATEX for Series Data

For sparklines and multi-point charts, build coordinate strings with CONCATENATEX:

VAR _Points = CONCATENATEX(
    _SparklineTable,
    [X] & "," & (100 - [Y]),
    " ",
    [Date], ASC
)
-- Produces: "0,80 10,60 20,40 30,20"
-- Use in: <polyline points='...'/>

Best Practices

  • Check UDF libraries first -- use DaxLib.SVG or MacGuyver Toolbox functions before writing custom DAX
  • VAR pattern mandatory -- one VAR per config value, one VAR per SVG element, assembly at the end
  • Normalize all values -- raw measure values must be scaled to SVG coordinate range
  • HASONEVALUE guard -- always guard against total/subtotal rows in table/matrix context; use ISINSCOPE for nested hierarchy levels
  • <desc> sort trick -- embed formatted value in <desc> for sortable SVG columns
  • Use viewBox for responsive scaling instead of fixed width/height
  • Round coordinates to integers for performance (shorter strings, cheaper FORMAT calls)
  • Store as extension measures -- SVG measures don't belong in the semantic model
  • Use display_folder to organize SVG measures (e.g., "SVG Charts")
  • Preview first -- save static SVG to /tmp/, open in browser, iterate before writing DAX
  • 32K character limit on the rendered SVG string per cell (not the DAX expression); see references/svg-table-matrix.md for diagnosis and mitigation
  • Pre-aggregate in model measures -- let the storage engine cache aggregations; the SVG measure maps numbers to coordinates only
  • Hex colors only -- # directly, never %23 URL encoding
  • Image visuals need no query block -- only objects.image with sourceType='imageData' and sourceField
  • Accessibility: every SVG encoding primary data needs adjacent readable columns and a dynamic alt-text measure; see references/svg-accessibility.md

Limitations

  • No interactivity -- SVG images are static (no hover, click, tooltip)
  • No JavaScript -- inline scripts are stripped
  • 32K character limit per rendered cell string (not the DAX expression); CONCATENATEX over 30+ series points easily approaches this; prefer <polyline> over individual shapes, integer coordinates, and pre-aggregated series; see references/svg-table-matrix.md for full diagnosis
  • Per-cell formula-engine cost -- each visible cell evaluates the string-building expression; push aggregations into model measures so SVG assembly is coordinate-mapping only
  • Accessibility gap -- screen readers receive no per-cell data from an SVG URI; mitig

# SVG Visuals via DAX Measures (PBIR)

> **Use `pbir` for every report mutation.** The `pbir-format` skill is read-only schema context.
> If the CLI is unavailable or lacks an operation, stop and report the gap.

Generate inline SVG graphics using DAX measures that return SVG markup strings. These render as images in table, matrix, card, image, and slicer visuals. Store as extension measures in `reportExtensions.json`.

## How It Works

1. A DAX measure returns an SVG string prefixed with `data:image/svg+xml;utf8,`
2. The measure's `dataCategory` is set to `ImageUrl`
3. Power BI renders the SVG as an image in supported visuals

## Supported Visuals

- Table (`tableEx`): `grid.imageHeight` / `grid.imageWidth` -- `references/svg-table-matrix.md`
- Matrix (`pivotTable`): same as table -- `references/svg-table-matrix.md`
- Image (`image`): `sourceType='imageData'` + `sourceField` -- `references/svg-image-visual.md`
- Card/New (`cardVisual`): `callout.imageFX` -- `references/svg-card-slicer.md`
- Slicer/New (`advancedSlicerVisual`): header images -- `references/svg-card-slicer.md`

## Workflow: Creating an SVG Measure

### Step 0: Design and Preview

Before writing DAX, design the SVG visually:

1. **Query the model first** -- use DAX Studio or Tabular Editor CLI to get actual values with the intended filter context. Use real numbers, not placeholders.
2. **Write static SVG to a temp file** -- save to `/tmp/mockup.svg` and `open` it in a browser to preview layout, colors, and proportions.
3. **Ask for feedback** before converting to DAX -- iterating on static SVG is far easier than on DAX string concatenation.
4. **Colors must be hex codes with `#`** -- e.g., `fill='#2B7A78'`. Never use `%23` URL encoding or named colors. Always hex.

### Step 1: Create the Extension Measure

Create the extension measure in `reportExtensions.json` manually (see the `pbir-format` skill in the pbip plugin for JSON structure).

```python
# Example using pbir_object_model (if available):
report.add_extension_measure(
    table="Orders",
    name="Sparkline SVG",
    expression='''
        VAR _Prefix = "data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 100 30'>"
        VAR _Bar = "<rect x='0' y='0' width='50' height='30' fill='#2196F3'/>"
        VAR _Suffix = "</svg>"
        RETURN _Prefix & _Bar & _Suffix
    ''',
    data_type="Text",
    data_category="ImageUrl",
    display_folder="SVG Charts",
)
report.save()
```

### Step 1b: Review

Before presenting the measure to the user, dispatch the `svg-reviewer` agent to validate syntax and provide design feedback.

### Step 2: Bind to a Visual

Extension measures use `"Schema": "extension"` in the SourceRef:

```json
{
  "field": {
    "Measure": {
      "Expression": {
        "SourceRef": {"Schema": "extension", "Entity": "Orders"}
      },
      "Property": "Sparkline SVG"
    }
  }
}
```

For **image visuals**, bind the SVG measure through `pbir add visual image --image`; see
`references/svg-image-visual.md`.

### Step 3: Validate

Validate with `pbir validate "Report.Report" --all` and inspect bindings with
`pbir visuals bind "...Visual" --show`.

## Prefer UDF Libraries Over Custom DAX

Before writing a custom SVG measure from scratch, check whether an existing UDF library already provides the chart type:

- **PowerofBI.IBCS** (Andrzej Leszkiewicz) -- IBCS-compliant bar, column, waterfall, pin, small multiples, and P&L charts. Preferred for business reporting with AC/PY/BU/FC comparisons. Install from https://daxlib.org/package/PowerofBI.IBCS/
- **DaxLib.SVG** (Jake Duddy) -- general-purpose sparklines, bars, boxplots, heatmaps, jitter, violin, progress bars, pills. Install from https://daxlib.org/package/DaxLib.SVG/ -- source at https://github.com/daxlib/dev-daxlib-svg
- **PowerBI MacGuyver Toolbox** (Stepan Resl / Data Goblins) -- C# scripts that generate SVG measures via Tabular Editor

To check if a library is installed, look for functions/measures starting with `PowerofBI.IBCS.`, `Viz.`, `Compound.`, or `Element.`. Only write custom SVG DAX when no library function covers the required visualization. See `references/community-examples.md` for full function listings and additional libraries.

### Installing UDF libraries

UDF libraries are installed into the semantic model, not the report. Use one of these tools:

- **Tabular Editor CLI** (`te` command) -- use the `te-docs` skill for guidance
- **Power BI MCP server** -- if available, use it to modify the model directly
- **`connect-pbid` skill** -- connect to Power BI Desktop's local Analysis Services instance via TOM/PowerShell

-- SVG ELEMENTS: One VAR per visual element
VAR _SvgPrefix = "data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 100 25'>"

VAR _Bar = "<rect x='0' y='5' width='" & _ActualNormalized & "' height='15' fill='" & _BarColor & "'/>"
VAR _TargetLine = "<rect x='" & DIVIDE( _Target, _AxisMax ) * _AxisRange & "' y='2' width='2' height='21' fill='" & _TargetColor & "'/>"
VAR _SvgSuffix = "</svg>"

-- ASSEMBLY: Combine in rendering order (back to front)

- **CONFIG section first** -- input measures, scope column, colors, font settings. Users change only this section.
- **NORMALIZATION section** -- scale raw values to SVG coordinate space (see below)
- **SVG ELEMENTS** -- one VAR per `<rect>`, `<circle>`, `<text>`, `<line>`, etc.
- **ASSEMBLY** -- concatenate elements in document order (first = back layer, last = front)
- **`<desc>` sort trick** -- embed `FORMAT(_Actual, "000000000000")` in a `<desc>` tag so the table/matrix can sort by the SVG column

### Axis Normalization (Critical)

SVG coordinates must be normalized to a fixed range. Raw measure values (e.g., 1,234,567) cannot be used directly as pixel coordinates. The standard pattern:

VAR _AxisMax = _MaxInScope * 1.1   -- 10% padding

-- 3. Normalize each value to the SVG range
VAR _AxisRange = _BarMax - _BarMin
VAR _Normalized = DIVIDE( _Actual, _AxisMax ) * _AxisRange
```

Use `ALLSELECTED` for the scope when the chart should respond to slicer context. Use `ALL` for a fixed axis across all filter contexts. The `* 1.1` padding prevents bars from touching the edge.

### Escaping and Color Rules

- **Single quotes for SVG attributes** -- avoids DAX double-quote escaping: `fill='#2196F3'`
- **Double quotes in DAX**: escape as `""` (DAX convention)
- **`viewBox`** for responsive scaling: `viewBox='0 0 100 25'`
- **`xmlns`** required on `<svg>` element
- **Hex colors with `#` only** -- e.g., `fill='#2196F3'`. `%23` URL encoding causes errors in image visuals. Never use named colors.
- **No JavaScript** -- SVG must be purely declarative

### SVG Coordinate System

- Y=0 is at the **top** -- invert values for charts: `_Height - _Value`
- Use `viewBox` with a 0-100 range for normalized coordinates
- Elements render in document order (first = back, last = front)

### CONCATENATEX for Series Data

For sparklines and multi-point charts, build coordinate strings with CONCATENATEX:

```dax
VAR _Points = CONCATENATEX(
    _SparklineTable,
    [X] & "," & (100 - [Y]),
    " ",
    [Date], ASC
)
-- Produces: "0,80 10,60 20,40 30,20"
-- Use in: <polyline points='...'/>

  • Permission surface may require sandboxing
  • The skill depends on external CLI tools (pbir, Tabular Editor) and references other skills (pbir-format, te-docs) that are not included in this repository, which may cause friction if those tools are unavailable.
  • The skill does not explicitly address potential security risks of using third-party UDF libraries, though it does recommend checking for them before writing custom DAX.
  • Quality score needs review
  • Permission surface needs review: shell or command execution, filesystem or document access
