When to use this template
A sunburst chart effectively reveals the proportional contribution of hierarchical segments to a whole, allowing for exploration of part-to-whole relationships across multiple levels. Analysts use it to identify dominant categories at various depths and understand how higher-level aggregates break down into their constituent parts.
- Hierarchical data with nested categorical levels
- Each node possessing a quantitative value for proportional sizing
- Datasets where part-to-whole relationships across a hierarchy are key
- Moderate number of top-level categories, supporting deep sub-category exploration
- Values representing additive quantities or cumulative measures
- Data where drilling down into specific branches is a primary analytical task
