## What it is
amCharts 4 is an advanced JavaScript and TypeScript charting library for the web, supporting 60+ chart types including XY charts, pie charts, gauges, Sankey diagrams, treemaps, and interactive geographical maps. It is a mature, battle-tested commercial product (with a freeware backlink option) that renders SVG-based interactive visualizations with built-in legends, zoom, tooltips, and accessibility support.

## Use cases
- add interactive charts to a javascript web app
- render pie and bar charts from  data
- build interactive world or country maps in the browser
- create sankey and chord flow diagrams
- display stock charts with indicators and annotations
- make accessible wcag-compliant data visualizations
- embed gantt charts in a web dashboard
- visualize hierarchical data with treemap or sunburst

## When to choose
- you need a polished, feature-complete charting engine with 60+ chart types out of the box
- you need interactive maps with drill-down navigation
- accessibility compliance (Section 508, WCAG) is a requirement
- you want battle-tested, commercially supported software with long-term maintenance
- you need TypeScript-first typings and framework integrations (React, Angular, Vue, Ember)

## When to avoid
- you need a fully open-source library with a permissive license like MIT (amCharts requires a commercial license or a freeware backlink)
- you want a lightweight, minimal charting solution with a small bundle size
- you prefer community-driven libraries like Chart.js, ECharts, or D3
- you are starting a new project and can adopt the newer amCharts 5 instead of this legacy version
