--- name: syncfusion-maui-sunburst-charts description: Implements Syncfusion .NET MAUI Sunburst Chart (SfSunburstChart) for hierarchical data visualization using a radial, multi-level circular layout. Use this for sunburst charts, radial hierarchical charts, multi-level pie charts, or hierarchical data visualization with drill-down capabilities. Ideal for visualizing organizational structures, file systems, or nested categorical data. metadata: author: "Syncfusion Inc" version: "33.1.44" --- # 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 ## Documentation and Navigation Guide ### Getting Started 📄 **Read:** [references/getting-started.md](references/getting-started.md) - NuGet package installation and setup - Basic sunburst chart implementation - Creating hierarchical data models - Configuring ItemsSource and ValueMemberPath - Adding hierarchical levels with GroupMemberPath - Enabling title, legend, tooltips, and labels - Complete working example ### Visual Customization #### Appearance Configuration 📄 **Read:** [references/appearance.md](references/appearance.md) - Adjusting start and end angles for partial circles - Customizing radius and inner radius - Configuring stroke color and width - Creating donut-style visualizations #### Data Labels 📄 **Read:** [references/data-labels.md](references/data-labels.md) - Enabling and positioning data labels - Overflow modes (Trim, Hide) - Rotation modes (Angle, Normal) - Font customization (family, size, color, attributes) ### Interactivity Features #### Tooltips 📄 **Read:** [references/tooltips.md](references/tooltips.md) - Enabling tooltips for segment details - Customizing tooltip appearance - Creating custom tooltip templates - Configuring display duration and styling #### Selection 📄 **Read:** [references/selection.md](references/selection.md) - Selection types (Single, Child, Group, Parent) - Display modes (Brush, Opacity, Stroke) - Selection events (SelectionChanging, SelectionChanged) - Highlighting selected segments and related hierarchies #### Drill-Down 📄 **Read:** [references/drill-down.md](references/drill-down.md) - Enabling interactive drill-down navigation - Toolbar alignment and positioning - Customizing drill-down toolbar appearance - Zoom-back and reset operations ### Advanced Features #### Center View 📄 **Read:** [references/center-view.md](references/center-view.md) - Adding custom views to chart center - Using CenterHoleSize for proper sizing - Creating summary displays in center - Complex layouts with borders and labels #### Liquid Glass Effect 📄 **Read:** [references/liquid-glass-effect.md](references/liquid-glass-effect.md) - Modern glass design styling (.NET 10+) - Wrapping charts in SfGlassEffectView - Enabling glass effect on tooltips - iOS/macOS platform-specific features
