Apache ECharts is a free, open-source charting and data visualization library written in pure JavaScript, designed to enable developers to add interactive and highly customizable charts to web applications and commercial products. Built on zrender, a lightweight canvas library, ECharts provides an extensive toolkit for creating everything from basic statistical charts to complex interactive dashboards and real-time data visualizations. The library supports both canvas and SVG rendering, giving developers flexibility in choosing the rendering approach that best suits their performance and compatibility requirements.
The repository is classified across multiple domains reflecting its broad applicability: data visualization, interactive graphics, statistical analysis, business intelligence, dashboard creation, and real-time plotting. ECharts serves as both a standalone charting library and a foundational component for building analytics tools and web-based visualization frameworks. The library's customizable themes and cross-platform support make it suitable for diverse use cases ranging from simple web analytics to complex business intelligence applications.
Distribution of the library is handled through multiple channels including direct download from the official website at echarts.apache.org, npm package installation, and CDN delivery via jsDelivr. Comprehensive documentation is available including a handbook for getting started, detailed API documentation, an option manual for configuration, and an extensive collection of examples demonstrating various chart types and interactive features.
The project maintains active community engagement with dedicated support channels including GitHub Issues for bug reports and feature requests, a development mailing list for project updates, and email support at [email protected] for general inquiries.
The repository's contributor base overlaps with major projects including Microsoft's VSCode and TypeScript implementations, as well as the Rust language project, suggesting ECharts attracts developers working across diverse technology stacks.
The project provides several official extensions expanding its capabilities: ECharts GL for 3D visualizations and WebGL acceleration, Liquidfill for specialized chart types, Wordcloud for text visualization, and a Baidu Map extension for geographic data visualization. Community integrations include vue-echarts for Vue.js applications and echarts-stat for statistical analysis. The library is distributed under the Apache License V2 and adheres to the Apache Code of Conduct, reflecting its status as an Apache Software Foundation project.
