@grafana/flamegraph

Flame-graph rendering component used by profiling datasources. Source under packages/grafana-flamegraph/.

Scope

<FlameGraph> is a high-performance canvas-based renderer for stack traces / profile data. It is shared between:

• public/app/plugins/datasource/grafana-pyroscope-datasource/ (Pyroscope).
• public/app/plugins/datasource/parca/ (Parca).
• The Explore Profile / FlameGraph view.
• Continuous profiling integrations.

What it does

• Accepts a profile in the DataFrame shape produced by the backend datasources (level, value, label, self).
• Renders the inverted flame graph with hover, search, and zoom.
• Emits selection events so the host can show a sandwich view, or jump to source.

Why a separate package?

Flame graphs are useful well beyond a single panel — they show up in plugin admin (size analysis), in profiling drilldowns, and as a top-level Explore visualization. Shipping them as a package keeps the implementation single-sourced and lets external plugins consume the same component for their own profile data.
