# Implementing .NET MAUI Sunburst Charts
Guide users to implement Syncfusion .NET MAUI Sunburst Chart (SfSunburstChart), a powerful hierarchical data visualization component that displays multi-level categorical data in a radial layout. Each ring represents a level in the hierarchy, with segments sized proportionally to their values. The component supports interactive drill-down, customizable appearance, data labels, tooltips, selection, and modern liquid glass effects.
## When to Use This Skill
Use the Syncfusion .NET MAUI Sunburst Chart when you need to:
- **Visualize hierarchical data** with 2-5 levels (organizational charts, file systems, product categories)
- **Show proportional relationships** where segment size represents value or count
- **Enable drill-down exploration** of large hierarchical datasets with interactive navigation
- **Display nested categorical data** like sales by region → department → product
- **Create radial visualizations** as an alternative to tree maps or nested pie charts
- **Build interactive dashboards** with multi-level data exploration capabilities
The sunburst chart is ideal when users need to understand both the hierarchy structure and the relative proportions at each level.
## Component Overview
The SfSunburstChart presents hierarchical data in concentric rings, where:
- **Center** represents the root or can display custom content
- **Inner rings** represent higher-level categories
- **Outer rings** represent detailed subcategories
- **Segment size** is determined by the value property
- **Drill-down** allows focusing on specific branches
**Key capabilities:**
- Hierarchical level configuration with GroupMemberPath
- Customizable angles, radius, and inner radius
- Data labels with rotation and overflow modes
- Interactive tooltips with custom templates
- Selection highlighting with multiple display modes
- Drill-down with animated toolbar navigation
- Center view for displaying summary information
- Liquid glass effect for modern iOS/macOS styling
