amcharts

20 years of hard-won knowledge about charts, data, edge cases, and human perception — packaged into a JavaScript library for charts, maps, stock charts and Gantt. Free to use, even commercially.

Then you'll need an interactive legend. Then zoom and scroll. Then responsive layouts on mobile. Then accessible labels. Then data grouped into weeks and months automatically. Then smooth transitions between datasets.

Each requirement means another prompt. Each prompt introduces new bugs. You end up debugging AI output instead of shipping your product.

Tell AI to use amCharts and all of the above comes built in. No extra prompts, no fragile workarounds — a real charting engine does the heavy lifting.
