ECharts is a JavaScript data visualization library and web charting framework used to render interactive 2D and 3D data plots within a web browser. It functions as a visualization engine that transforms raw data into customizable charts and graphs.
The project includes a WebGL-based hardware acceleration engine specifically for producing three-dimensional plots and globe visualizations. This allows the library to handle large and complex datasets through GPU-accelerated rendering.
The framework supports both canvas-based raster rendering and SVG-based vector rendering. It provides capabilities for interactive data visualization and web analytics dashboarding, utilizing an event-driven interaction system to allow users to explore datasets directly in the browser.
