A heuristic extending the Squarified treemapping algorithm
This work addresses an incremental improvement in visualization techniques for users needing clearer treemap layouts, such as in data analysis or software engineering.
The paper tackled the problem of improving the Squarified treemapping algorithm for hierarchical data visualization by introducing new heuristic steps, resulting in treemaps with better aspect ratios and higher homogeneity among items while maintaining low computational impact.
A heuristic extending the Squarified Treemap technique for the representation of hierarchical information as treemaps is presented. The original technique gives high quality treemap views, since items are laid out with rectangles that approximate squares, allowing easy comparison and selection operations. New key steps, with a low computational impact, have been introduced to yield treemaps with even better aspect ratios and higher homogeneity among items.
