Diffusion Cartograms for the Display of Periodic Table Data
Mapping methods employed by geographers, known as diffusion cartograms (diffusion-based density-equalizing maps), are used to present visually interesting and informative plots for data such as income, health, voting patterns, and resource availability. The algorithm involves changing the sizes of geographic regions such as countries or provinces so that they appear in proportion to the property in question while maintaining topographic integrity. These methods are employed here to portray numerical data properties of the elements. The periodic table is treated as a ?map? of square ?countries? and distorted using a diffusion cartogram algorithm to display periodic properties.
