What This Skill Does
Generates charts from data using the Chart Splat API, returning PNG images rendered server-side with Chart.js. Supports line, bar, pie, doughnut, radar, polar area, candlestick, and OHLC chart types. Charts are created via a CLI command or a helper script.
No local rendering setup required — the API handles Chart.js server-side and returns a ready-to-use PNG file.
