Blazor Sunburst Chart Default Functionalities Example

This Blazor Sunburst Chart example visualizes the top universities from the QS World University Rankings 2026, grouped by region and country.

In this example, you can see how to render and configure a sunburst chart. The sunburst chart is ideal for displaying hierarchical data where each ring represents a level in the hierarchy. Key features demonstrated here include:

• Title and SubTitle to provide a heading and source for the chart
• Radius set to 0.9 to give the chart a slightly inset frame inside the available area
• SunburstDataLabelSettings with LabelRotationMode set to Angle and LabelOverflowMode set to Trim to keep labels readable along the radial layout
• SunburstTooltipSettings with EnableHighlight set to true to show the value and category of a segment on hover and emphasize the hovered segment
• A custom Palette aligned to the active theme to color the rings consistently

Tooltip is enabled in this example. To see tooltip details, hover over or tap on a segment.
