Teaches the one-tool embedding contract (call chart_render → live chart appears in chat AND a downloadable PNG lands in the queen session dir), the ECharts (data viz) vs Mermaid (structural diagrams) decision, the BI/financial-grade aesthetic baseline (no chartjunk, restrained palette, proper typography, single message per chart), and the canonical spec patterns for the 12 most-common chart types. Skipping this leads to 1990s-Excel charts, missing downloads, and the agent writing markdown image links by hand instead of letting chart_render drive the UI.\nmetadata:\n  author: hive\n  type: preset-skill\n  version: \"1.0\"\n---\n\n# Chart creation foundations\n\nThese tools render BI/financial-analyst-grade charts and diagrams that show up live in the chat AND save as high-DPI PNGs in the user's queen session dir.\n\n## The embedding contract — one rule\n\n> **To put a chart in chat, call `chart_render`. The chat reads `result.spec` and renders the chart live in the message bubble. The download link is `result.file_url`. Do not write `![chart](...)` image markdown by hand — the tool's result drives the UI.**\n\nThat's it. One tool call, one chart in chat, one file on disk. No two-step \"remember to also save it\" pattern. The chat's chart-rendering UI is fed by the tool result envelope automatically.\n\n## When to chart at all\n\nChart when the data is **visual at heart**: trends over time, distributions, comparisons across categories, hierarchies, flows, geo. Skip the chart when:\n\n- The point is one number → just say it. (\"Revenue was $4.2M, up 12% YoY.\")\n- The point is a ranking of 5 things → use a markdown table with bold and emoji indicators.\n- The data is so noisy a chart would mislead → describe the takeaway in prose.\n\nA chart costs the user attention. It must repay that cost with a takeaway they couldn't get from prose.\n\n## ECharts vs Mermaid — the picking rule\n\n| Use ECharts (`kind: \"echarts\"`) when... | Use Mermaid (`kind: \"mermaid\"`) when... |\n|---|---|\n| You're plotting **numbers over categories or time** | You're showing **structure, not data** |\n| Bar / line / area / scatter / candlestick / heatmap / treemap / sankey / parallel coordinates / calendar / gauge / pie / sunburst / geo map | Flowchart / sequence / gantt / ERD / state diagram / mindmap / class diagram / C4 architecture |\n| The viewer's question is \"how much / how many / what's the trend\" | The viewer's question is \"what calls what / what depends on what / what happens after what\" |\n\nIf both fit (rare), prefer ECharts — its rasterized output is a proper data chart for slides; Mermaid's diagrams are for technical docs.\n\n## The aesthetic baseline (non-negotiable)\n\nThese are the rules that turn an Excel-default chart into a Tableau-grade one. Every chart you produce must follow them.\n\n### 1. Theme & background\n- `chart_render` has **no `theme` parameter**. The renderer reads the user's UI theme from the desktop env (`HIVE_DESKTOP_THEME`) so the saved PNG matches what the user is actually looking at. You don't pick; the system does.\n- Title goes in `option.title.text`, NOT in the message body. The chart is self-contained.\n\n### 2. Palette discipline — DO NOT set `color` on series\n\nThe OpenHive ECharts theme is auto-applied to every `chart_render` call. It defines:\n- An 8-hue **categorical palette** for multi-series charts (honey orange, slate blue, sage, terracotta, bronze, indigo, olive, rust)\n- Cozy spacing (`grid.top: 90`, `grid.bottom: 56`, etc.)\n- Brand typography (Inter Tight)\n- Tasteful axis lines + dashed gridlines\n\n**Do not set `option.color`, `option.title.textStyle`, `option.grid`, or `option.itemStyle.color` on series.** The theme covers it. If you do override, you'll fight the brand palette and the chart will look generic.\n\nWhen you need data-encoded color (NOT category color):\n- **Sequential** (magnitude): use `visualMap` with `inRange.color: ['#fff7e0', '#db6f02']` (light-to-honey)\n- **Diverging** (positive/negative): use `visualMap` with `inRange.color: ['#a8453d', '#f5f5f5', '#3d7a4a']` (terracotta/neutral/sage)\n- **Semantic up/down** (candlestick is auto-themed): for explicit gain/loss bars use `#3d7a4a` (gain) and `#a8453d` (loss), NOT `#27ae60` / `#e74c3c`.\n\n### 3. Typography\nThe default font (`-apple-system, \"Inter Tight\", system-ui`) is already wired in the renderer — don't override unless the user asked. Set `option.textStyle.fontSize: 13` for body labels, `16` for axis names, `18` bold for the title.\n\n### 4. No chartjunk\n- **No 3D**. Ever. 3D pie charts and 3D bar charts are visual lies.\n- **No drop shadows** on bars or lines. The default flat ECharts look is correct.\n- **No gradient fills** unless the gradient encodes data (e.g. heatmap fill).\n- **No neon colors**. Saturation belongs on highlighted bars, not on every series.\n- **No more than 5 stacked colors** in a stacked bar — past that the eye can't separate them.\n\n### 5. Axis hygiene\n- X-axis labels rotate 45° only when they overflow. Otherwise horizontal.\n- Y-axis starts at 0 for bar/area charts (truncating misleads). Line charts can start at min - 5%.\n- Use `option.yAxis.axisLabel.formatter: '{value} M'` to add units, NOT a separate \"USD millions\" subtitle.\n- Date axes: pass ISO strings (`\"2024-01-15\"`) and ECharts handles the layout. Use `xAxis.type: \"time\"`.\n\n### 6. One message per chart\nEvery chart goes in its own assistant message (or its own `chart_render` call). Do not pile 4 charts into one wall of tool calls — the user can't focus and the chat gets noisy.\n\n## Calling `chart_render` — the canonical pattern\n\n```\nchart_render(\n  kind=\"echarts\",\n  spec={\n    \"title\": {\"text\": \"Q4 revenue by region\", \"left\": \"center\"},\n    \"tooltip\": {\"trigger\": \"axis\"},\n    \"xAxis\": {\"type\": \"category\", \"data\": [\"NA\", \"EU\", \"APAC\", \"LATAM\"]},\n    \"yAxis\": {\"type\": \"value\", \"axisLabel\": {\"formatter\": \"${value}M\"}},\n    \"series\": [{\"type\": \"bar\", \"data\": [12.4, 8.7, 5.3, 2.1], \"itemStyle\": {\"color\": \"#db6f02\"}}]\n  },\n  title=\"q4-revenue-by-region\",\n  width=1600, height=900, dpi=300\n)\n```\n\nReturns:\n```\n{\n  \"kind\": \"echarts\",\n  \"spec\": {...echoed...},\n  \"file_path\": \"/.../charts/2026-04-30T...q4-revenue-by-region.png\",\n  \"file_url\": \"file:///.../q4-revenue-by-region.png\",\n  \"width\": 1600, \"height\": 900, \"dpi\": 300, \"bytes\": 142318,\n  \"title\": \"q4-revenue-by-region\", \"runtime_ms\": 287\n}\n```\n\nThe chat panel reads `result.spec` and mounts ECharts in the message bubble. The user sees the chart immediately. The PNG is on disk and the chat shows a download link from `result.file_url`. **You don't write that link — it appears automatically.**\n\n## The 12 chart types you'll use 95% of the time\n\n| When | ECharts type | Notes |\n|---|---|---|\n| Trend over time | `series.type: \"line\"` | Smooth = `smooth: true` only when data is noisy |\n| Multi-metric trend | Two `line` series with `yAxis: [{}, {}]` | Separate scales when units differ |\n| Category comparison | `series.type: \"bar\"` | Sort by value descending, not alphabetically |\n| Stacked composition | `bar` with `stack: \"total\"` | Cap at 5 categories |\n| Distribution | `series.type: \"boxplot\"` or `bar` of bins | Boxplot for ≥3 groups; histogram for one |\n| Two-variable correlation | `series.type: \"scatter\"` | Add `regression` markline if relevant |\n| Candlestick / OHLC | `series.type: \"candlestick\"` | Date axis + `dataZoom` range slider |\n| Geo distribution | `series.type: \"map\"` | Bundled `world` and country GeoJSONs |\n| Hierarchy / share | `series.type: \"treemap\"` or `sunburst` | Use treemap for >12 leaves; pie only for 2-5 |\n| Flow | `series.type: \"sankey\"` | Names matter — keep them short |\n| Calendar density | `series.type: \"heatmap\"` + `calendar` | Daily metrics over a year |\n| KPI scorecard | `series.type: \"gauge\"` | Set `min`, `max`, threshold band |\n\nWorked specs for each are in `references/` — paste, modify, render.\n\n## Mermaid quick rules\n\n```\nchart_render(\n  kind=\"mermaid\",\n  spec=\"\"\"\nflowchart LR\n  A[Customer signs up] --> B{Onboarded?}\n  B -- yes --> C[Activate trial]\n  B -- no --> D[Email reminder]\n\"\"\",\n  title=\"signup-flow\"\n)\n```\n\n- One diagram per chart_render call.\n- Keep node labels short (≤20 chars).\n- Use `flowchart LR` for left-to-right; `TD` for top-down. LR reads better in a chat bubble.\n- For sequence diagrams, indicate async with `->>` (open arrow) and sync return with `-->>` (dashed).\n- Don't try to encode data in mermaid (no widths, no quantities) — that's an ECharts job.\n\n## Common mistakes the agent makes\n\n1. **Writing `![chart](file://...)` markdown by hand.** Don't. The chat renders from the tool result automatically. Manual image markdown will display nothing (file:// is blocked from arbitrary chat content).\n2. **Calling chart_render twice for the same chart \"to embed and to save\".** Only one call. The single call does both.\n3. **Overriding fonts to fancy display faces.** Stay with the default; the agent's job is data, not typography.\n4. **Pie charts with 12 slices.** Use a horizontal bar chart sorted by value. Pie is only for 2-5 mutually-exclusive shares.\n5. **Forgetting `axisLabel.formatter` for currency / percentage.** A y-axis showing \"12000000\" is unreadable; \"12M\" is correct.\n6. **Putting a chart's title in the message body.** Set `option.title.text` instead so the title is part of the saved PNG.\n","tagline":"Required reading whenever any chart_* tool is available.
