An Approach to Generate Spatial Voronoi Treemaps for Points, Lines, and Polygons

An Approach to Generate Spatial Voronoi Treemaps for Points, Lines, and Polygons

As a space-filling method, Voronoi Treemaps are used for showcasing hierarchies. Previously presented algorithms are limited to visualize nonspatial data. The approach of spatial Voronoi Treemaps is proposed in this paper to eliminate these problems by enabling the subdivisions for points, lines, an...
