For a few years now, it has become easy to create interactive maps with R thanks to the package leaflet by the Rstudio team. Nevertheless, it only provides only a few functions to create basic shapes on a map, so the information that can be represented on a single map is limited: if you have some data associated to some points, you can only represent at most two variables by drawing circles and changing their radius and color according to data. leaflet.minicharts is an R package that provides two functions to add and update small charts on an interactive maps created with the package leaflet. These charts can be used to represent as many variables as desired associated to geographical points. Currently, three types of chart are supported: barcharts (the default), pie charts and polar area charts (with two variants: "polar-area" and "polar-radius", where values are represented respectively by the area or the radius of the slices).
