prism-chart — Chart & Visualization Selection

Name: prism-chart
Author: tonone-ai

Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.

When to use

User needs a chart implementation, visualization type recommendation, or data display component.

Workflow

Identify data type from user request (time series, comparison, distribution, composition, relationship, etc.)

Search chart knowledge base:

python3 -m prism_agent.uiux search --domain chart --query "{data_type}" --limit 3

Evaluate results for: data volume threshold, accessibility grade, interaction level
Output recommendation with library choice and accessibility fallback

Output format

┌─ Chart Recommendation — {data_type} ────────────────────────────────┐
│ Chart type:        {chart_type}                                      │
│ Library:           {library} (Chart.js / Recharts / D3 / Plotly)    │
│ Accessibility:     {grade} (AA / A / Below AA)                      │
│ Interaction level: {level} (static / hover / drill-down)            │
│ Data volume:       {threshold} (max recommended data points)        │
├─ Color guidance ────────────────────────────────────────────────────┤
│ {color_guidance}                                                     │
├─ Accessibility fallback ────────────────────────────────────────────┤
│ {fallback_description}                                               │
└──────────────────────────────────────────────────────────────────────┘

Anti-patterns

Never ignore data volume threshold — recommend aggregation if data exceeds it
Never skip accessibility fallback for charts graded below AA
Never choose a chart type based on visual appeal over data clarity
Never recommend a library without confirming it is compatible with the detected stack

Delivery

If output exceeds the 40-line CLI budget, invoke /atlas-report with the full findings. The HTML report is the output. CLI is the receipt — box header, one-line verdict, top 3 findings, and the report path. Never dump analysis to CLI.

Use it

Copy one of these into your project. Installing also returns the manifest and these snippets.

Manifest

An Open Capability Manifest: the router reads it to know what this does, what it costs and when to pick it.
