Sunburst

A sunburst chart visualizes hierarchical data using concentric rings. Use it to understand proportional breakdowns across levels.

A sunburst chart visualizes hierarchical data using concentric rings. It shows how a total metric is broken down across multiple levels.

It’s ideal for:

• memory breakdown per instance

• cost or usage hierarchy

• resource allocation

• drill-down analysis

What a sunburst represents

Each ring represents one level in the hierarchy.

• Center: root (total of all values)

• Inner ring: first hierarchy column

• Next rings: deeper hierarchy levels

• Slice size: proportional to metric value

• Color: category grouping

Sunburst chart

Configure a sunburst chart

Use the Plot panel to choose the hierarchy levels and the value column.

Sunburst chart options

Use these options to control how the sunburst chart renders.

Option	Purpose	Typical values / notes
Hierarchy columns (ordered)	Ordered levels for drill-down (inner → outer rings).	Examples: cluster → namespace → app, instance → pod → container, service → endpoint → status_code. Order matters.
Value column	Numeric metric used to size each slice.	Examples: value, memory_bytes, cost, request_count. Duplicate paths are aggregated.
Apply	Applies changes to the widget.	Changes do not render until you click Apply.

Key rules: at least one hierarchy column is required, hierarchy order matters (inner → outer), and Value column must be numeric.

When to use a sunburst chart

Use sunburst charts when:

• your data has multiple categorical levels

• you want visual drill-down

• you need proportional breakdown across hierarchy

They’re best for composition analysis (breakdowns), not trends.
