Diffusion Cartograms for the Display of Periodic Table Data

Autor: Mark J. Winter

Publikováno v: Journal of Chemical Education. 88:1507-1510

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 availabili
