Its organic shapes maintain a one-to-one aspect ratio, are \ufb02exible with their placement, allowing stable zooming and dynamic data values. In this paper, we present algorithms for ef\ufb01cient computation and dynamic update of Voronoi Treemaps. Our GPGPU-based technique allows for rapid computation of centroidal Voronoi Diagrams, providing almost two orders of magnitude speedup over previous work. In addition, we present a hierarchical algorithm for stable updates. Finally, we demonstrate the application of Voronoi treemaps to real-world dynamic datasets, including interactive navigation.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Abstract\u2014The Voronoi Treemap is a space-\ufb01lling treemap technique that relaxes the constraints of rectangular nodes.
