A disadvantage of choropleth maps is that they tend to distort the relationship between the true underlying geography and the represented variable. It is because the administrative divisions do not usually coincide with the geographical reality where people live. Besides, large areas appear to have a weight that they do not really have because of sparsely populated regions. To better reflect reality, more realistic population distributions are used, such as land use. With Geographic Information Systems techniques, it is possible to redistribute the variable of interest as a function of a variable with a smaller spatial unit.


Recently I was looking for a visual representation to show the daily changes of temperature, precipitation and wind in an application (in Spanish), which led me to use a heatmap in the form of a calendar. The shiny application is updated every four hours with new data showing calendars for each weather station.
