Zoomable Sunburst

Explore hierarchical data as concentric rings with interactive zoom. Each ring represents a level of the hierarchy, and arc width encodes value. Clicking an arc zooms into that subtree. Ideal for composition analysis, portfolio breakdowns, and any data with nested categories.

Examples

When to Use

• Showing proportional composition across multiple hierarchy levels simultaneously
• Portfolio or revenue breakdown by region, product, and sub-product
• Exploring nested categorical data interactively
• Comparing relative sizes within and across hierarchy levels

• Keep the hierarchy to 3-4 levels deep for optimal readability
