## What it is
Apache ECharts is a free, open-source JavaScript charting and data visualization library for the browser, built on the ZRender canvas engine. It offers 20+ interactive chart types, Canvas/SVG rendering, dataset-based data transforms, and accessibility features, and is highly customizable for commercial products.

## Use cases
- add interactive charts to a web dashboard
- render line, bar, and pie charts from a dataset
- visualize millions of data points in the browser
- create heatmaps, treemaps, and geographic map visualizations
- build responsive charts that work on mobile and desktop
- make accessible charts with automatic descriptions
- combine multiple chart types in one visualization

## When to choose
- you need a mature, feature-rich charting library with many chart types out of the box
- you must render very large datasets with progressive rendering
- you want Canvas and SVG rendering with a switchable engine
- you need a permissive Apache-2.0 license for commercial products
- you want built-in accessibility for charts

## When to avoid
- you need server-side static chart images only
- you want a minimal lightweight chart library with a tiny bundle
- you are building native mobile apps without a web view
- you prefer a declarative grammar-based visualization system like Vega-Lite
