Abstract

The tool represents an extension of the Geovisto library (via an npm package), providing a map layer that can be used to visualize choropleths. The map layer works with generic data and allows to visualize user-defined polygons representing geographical regions. Also, the solution implements various strategies for coloring polygons and finding optimal appearance emphasizing differences between the values of polygons. The map layer can be together with the filtering tools of the Geovisto library used to visualize the distribution of regions' values and their user-friendly comparison (e. g., the distribution of sources and share of regions in DDoS attack and network anomaly origin).
