Chart Generation

How It Works

Charts are generated server-side as PNG images using chartjs-node-canvas (Chart.js) and served via /api/media/. The generate-chart script renders charts and returns a fully qualified URL for embedding in chat markdown.

Script Usage

pnpm action generate-chart --type=bar --title="Title" --labels='["A","B","C"]' --data='[1,2,3]' --color="#18B4F4"
