Flame

Inspect original nested execution intervals.

Use a single-thread synchronous trace to inspect inclusive and self duration. The horizontal axis is original time; nesting controls depth. This is not an aggregated flamegraph or a concurrent scheduler.

data contains stable id, label, start, end and optional parentId. Finite endpoints use the same linear or UTC axis. Children must lie inside their parent; positive-duration siblings and roots must not overlap. Zero-duration events are valid. Maximum 2048 spans,32 depth levels; unknown parents and cycles are rejected.

layout.rowPadding controls spacing. Numeric viewport supports the X axis only. Function labels appear only when they fit. There is no visibility legend, stacking, shared tooltip or Y reference line. Units belong to data.axes.x; durations are not overwritten by global formatting.
