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

Song Tian, Ximin Cui, Yu Gong
2015 Journal of Electrical and Computer Engineering  
The approach of spatial Voronoi Treemaps is proposed in this paper to eliminate these problems by enabling the subdivisions for points, lines, and polygons with spatial coordinates and references.  ...  As a space-filling method, Voronoi Treemaps are used for showcasing hierarchies. Previously presented algorithms are limited to visualize nonspatial data.  ...  Conflict of Interests The authors declare that there is no conflict of interests regarding the publication of this paper.  ...

Visual Realism for the Visualization of Software Metrics

D. Holten, R. Vliegen, J.J. van Wijk

Visualization of the Static Aspects of Software: A Survey

Pierre Caserta, O Zendra
2011 IEEE Transactions on Visualization and Computer Graphics  
However, visualizing software is not an easy task because of the huge amount of information comprised in the software.  ...  Furthermore, the information content increases significantly once the time dimension to visualize the evolution of the software is taken into account.  ...  For instance, the house metaphor is composed of a cone for the roof and a cylinder for the body. Each visual characteristic of these two objects may represent a normalized software metric.  ...

Enhanced Spatial Stability with Hilbert and Moore Treemaps

S. Tak, A. Cockburn
2013 IEEE Transactions on Visualization and Computer Graphics  
An empirical study examines the validity and usefulness of the location drift metric, showing that it explains some effects on user performance that distance change does not.  ...  Treemaps are a well known and powerful space-filling visualisation method for displaying hierarchical data.  ...  For example, Voronoi treemaps [15] use arbitrary polygons rather than rectangles for visualising software metrics, and the Jigsaw layout [14] uses the space-filling H-curve [16] to create a treemap  ...
