chartPieSeparatorNone

A Charts block/component from shadcn/ui — clean-room reimplemented for Domphy (see methodology). Call chartPieSeparatorNone() with no arguments for a working demo, or edit the code below live.

Implementation notes

Implemented as chartPieSimple's full-disc layout with strokeWidth and padAngle exposed as explicit props defaulting to '0'/0 (no stroke attribute is even emitted when strokeWidth is '0'), matching the researchNote's guidance to keep this a configuration variant rather than a structurally different chart. Callers can pass non-zero values to re-enable separators. Same mount-sweep approximation caveat as chartPieSimple.

Status: ported · Reference: shadcn/ui original

// shadcn/ui "charts/pie-separator-none" — clean-room reimplementation.
//
// A pie/donut chart with zero border stroke and zero angular padding between
// adjacent wedges, so the colors blend into one seamless disc with no
// visible dividing lines. Functionally this is chartPieSimple with two
// prop flips (stroke width 0, pad angle 0), kept as an explicit variant so
// callers can see the "separator" knobs and re-enable them. Implemented
// purely from the block's public functional/visual spec — no upstream
// source was viewed.
