# `PhiaUi.Components.SunburstChart`
[🔗](https://github.com/charlenopires/PhiaUI/blob/v0.1.17/lib/phia_ui/components/data/sunburst_chart.ex#L1)

Sunburst chart for hierarchical data — pure SVG, zero JS.

Renders concentric rings where each arc represents a node in the hierarchy.
The angular span of each arc is proportional to its value. Children occupy
the same angular range as their parent but in the next outer ring.

## Examples

    <.sunburst_chart data={[
      %{label: "A", value: 40, children: [
        %{label: "A1", value: 25, children: []},
        %{label: "A2", value: 15, children: []}
      ]},
      %{label: "B", value: 30, children: [
        %{label: "B1", value: 30, children: []}
      ]},
      %{label: "C", value: 30, children: []}
    ]} />

    <.sunburst_chart
      data={hierarchy}
      ring_width={25}
      inner_radius={50}
      colors={["oklch(0.60 0.20 240)", "oklch(0.70 0.18 145)", "oklch(0.65 0.22 30)"]}
    />
