These maps display the density and distribution of a phenomena over a geographic area. The markers, usually a dot or cross, represent the occurrence or an aggregation of occurrences which are then randomly distributed across distinct regions of the map. Colours can be used to represent different classifications to add an extra dimension to the map.
The example above shows votes to remain (red) and leave (blue) the European Union in the London Boroughs. Each dot represents 100 votes and these have been randomly scattered within each borough to represent the density of votes. Continue reading “Creating a statistical dot density map with QGIS”
