An icicle chart is a hierarchical visualization that represents parent-child relationships with nested or stacked rectangular regions.
- How it is used
- Visualizes parent-child relationships through adjacency, especially in information-technology visualizations.
- How deep it goes
- Defines adjacency and identifies d3.partition() as the layout generator, but stops short of an icicle-specific implementation walkthrough.
- Examples
- Uses language families, branches, and speaker counts to demonstrate hierarchical data suitable for multiple chart forms.
- What you can do after
- Build it from scratch by converting CSV or JSON into root data, applying d3.partition(), and drawing the resulting layout in SVG.

An Icicle Graph is Parca's term for a flame-graph-style hierarchical visualization of profile data.
- How it is used
- Uses hierarchical profile views to navigate performance data and troubleshoot workloads through continuous profiling.
- How deep it goes
- Defines the inverted flame-graph form and profiling scope, but defers detailed chart-reading guidance to external material.
- Examples
- Demonstrates Parca profiling an OpenTelemetry collector and selecting Memory In-Use Bytes for visualization.
- What you can do after
- Operate Parca to select a profile and inspect its Icicle Graph for troubleshooting.
