Abstract

See full text

The invention notably relates to a computer-implemented method of designing a choropleth map, wherein the method comprises providing a map, and a number (n) of numerical values (x1, . . . , xn) that represent a statistical variable at respective areas of the map; computing the optimal K-means clustering of the numerical values for a predetermined number of clusters, wherein the computing includes iterating, a number of times corresponding to the predetermined number of clusters, a linear-time Row Minima Searching algorithm applied to a square matrix of order equal to the number of numerical values; assigning a respective coloration to each cluster of the computed clustering; and at all areas of the map at which a respective numerical value is provided, applying the coloration assigned to the cluster to which the respective numerical value belongs.
