Chart Coach — the right chart for your data

Paste a CSV or describe your data and what it should communicate. A free in-browser profiler types your columns, picks a heuristic chart and sketches it instantly; the AI then recommends the right chart form with exact encodings, the alternatives and why they lose, misleading-chart pitfalls, accessibility guidance, and runnable code for matplotlib, plotly, Vega-Lite, Recharts, D3 or ECharts.
