Geometric Marks

Family base entry: Geometric Marks, which opens with the Delaunay Links preset.

Example mark structure:

}

DelaunayLinks

Connects neighboring points by constructing a Delaunay triangulation, making it useful for showing proximity relationships, spatial neighborhoods, and point-to-point structure without manually defining every edge.

Voronoi Scatterplot

VoronoiScatterplot

Partitions the plotting area into Voronoi cells around each scatter point, helping readers see the nearest-point region for every observation and understand spatial influence or coverage across the chart.

Delaunay & Hull

DelaunayHull

Combines Delaunay triangulation with the convex hull boundary, showing both the internal neighborhood connections between points and the smallest enclosing outline that contains the full point set.
