Interactive JavaScript Charting Library

ApexCharts is an interactive charting library for JavaScript applications providing over 20 chart types including line, area, column, bar, candlestick, boxplot, timeline, range area, bubble, scatter, heatmap, treemap, pie, donut, radar, polar area, radialbar, gauge, funnel, slope, and sparkline visualizations. The library ships with over 15,000 GitHub stars and 6 million monthly npm downloads, with first-class framework wrappers for React, Vue, Angular, and Blazor that share the same configuration options across all frameworks. Charts are interactive by default, supporting zoom, pan, rich tooltips with crosshair tracking, series toggling, and data point annotations without additional configuration. Export capabilities allow users to download rendered charts as SVG, PNG, and CSV files directly from the browser. The ecosystem extends beyond basic charts with specialized products including ApexGrid for feature-rich data tables with sorting, filtering, inline editing, and virtual scrolling for large datasets, ApexGantt for interactive Gantt charts with drag-and-drop scheduling, dependencies, and milestone tracking, ApexTree for organizational charts and tree diagrams with collapse and expand, zoom, and pan, ApexSankey for flow diagrams with customizable nodes, gradient links, and path highlighting, and ApexStock for financial candlestick charts with technical indicators and drawing tools. Configuration uses a declarative options object where chart type, series data, axes configuration, and styling are specified, making integration straightforward with minimal code. Over 100 ready-to-use sample configurations are available in the documentation. The library works with AI coding assistants through dedicated skills installable for Claude Code, Cursor, and GitHub Copilot, providing context-aware chart code generation. Embedded analytics features support dashboard-building use cases within SaaS products.
