Explore Hierarchical Data with Sunburst Charts

June 25, 2026

LightningChart JS v8.3 introduces Sunburst charts, enabling intuitive exploration of hierarchical data with clear multi level part to whole insights.

LightningChart JS is a high-performance JavaScript charting library that utilizes WebGL rendering and GPU acceleration to deliver exceptional performance for a wide range of data visualization needs. It is designed to handle large datasets and complex visualizations with ease, enabling developers to create interactive and visually appealing 2D and 3D charts. Ideal for applications demanding smooth real-time data updates, such as financial platforms, engineering tools, scientific research dashboards, and industrial monitoring systems, LightningChart JS provides a comprehensive API for customization and integration into web-based projects.

The LightningChart JS v8.3 update introduces Sunburst charts, enabling developers to visualize hierarchical data in a compact and intuitive format that clearly represents part to whole relationships across multiple levels. By displaying nested categories as proportionally sized segments within concentric rings, the chart makes it easier to analyze complex data structures, compare contributions at different hierarchy levels, and identify patterns or dominant categories without requiring multiple visualizations. This helps developers deliver more informative data exploration experiences in applications that rely on organizational, financial, operational, or other structured datasets.

LightningChart JS is licensed per developer and is available as an annual license with 1 year support. See our LightningChart JS licensing page for full details.
