# Sunburst
The **Sunburst Chart** is a radial, multi-level hierarchical visualization ideal for displaying how values are distributed across nested categories.
It uses concentric rings to represent levels in a hierarchy, with each ring segment’s size proportional to its value.
**Use cases:**
- Representing **organizational hierarchies**
- Displaying **part-to-whole relationships** in nested data
- Visualizing **breakdowns within breakdowns** (like category → subcategory → sub-subcategory)

## ⚙️ Setup
1. Drag the **Sunburst Chart** widget from the chart library onto your designer workspace.
2. Select the chart.
3. Go to the [Widget Configuration](/insights-v8/guide-to-infoboard-designer/customize-panel/configure/) tab in the Configuration panel.
4. Under the Configuration panel tab, select the [Basic Configuration](/insights-v8/guide-to-infoboard-designer/customize-panel/configure/#basic) option to access essential settings for the Sunburst Chart.
5. Select the [Source](/insights-v8/guide-to-infoboard-designer/customize-panel/setup/#sources) from which the chart will fetch its data.
6. Map:
- **[Measure](/studio-v8/datasources/measures-dimensions-and-hierarchies/)** — Numeric value representing the size of each segment.
- **[Dimension](/studio-v8/datasources/measures-dimensions-and-hierarchies/)** — Sequential categorical fields representing hierarchy levels. Minimum of **2** and maximum of **4** levels.
7. Optionally add a **Date** field for time-based filtering.
