apache/echarts ? reverse-engineered prompt

Build me a browser charting library that can make clean, interactive, highly customizable charts for web apps.

It should support the usual chart types people expect, like line, bar, pie, scatter, and maps, and let me feed in data with a simple options object. I want smooth hover tooltips, legends, zooming, resizing, and the ability to switch between canvas and SVG rendering when it makes sense. Please make it easy to use in a normal website, and keep it flexible enough for commercial projects.

Also include a basic docs and examples setup so I can quickly see how to use it, plus a development workflow for running it locally, checking types, and building production files. If you need current implementation details, look up the latest docs online and match the project’s style.
