57.8 Point Markers, Scatter Plots, and Filled Areas🔗ℹ

A point-marker Visual stores one closed marker shape, local size, fill, stroke, affine transform, and opacity. A scatter plot is an ordered semantic group of such markers placed from numeric coordinates in an axes snapshot. Marker identities are deterministic and include the original input index. Gaps and clipped points are omitted without renumbering later markers.

A filled coordinate area is ordinary closed path geometry derived from accepted function-graph or ordered-data runs. Each visible run is closed to one horizontal numeric baseline. Discontinuous runs remain separate. Smooth interpolation keeps cubic graph segments rather than flattening them. Area Visuals store only geometry, style, transform, and opacity; they do not retain the sampling procedure or source list.
