) -> Option<Path<Pixels>>Expand description
Build the filled ribbon path for a link — the equivalent of d3-sankey’s
sankeyLinkHorizontal(): a horizontal cubic bezier with control points at
the horizontal midpoint, thickened to the per-end link widths (clamped to
min_width so tiny flows stay visible).
