topogRam

Make interactive cartograms with d3.js based on this example by Shawn Allen. I also used this example by Etienne Côme.

For France, boundaries come from OpenStreetMap, data from INSEE.

For USA, boundaries and data come from Shawn Allen's project

Warning : sizing is a little manual for the moment...

Installation

To install:

if (!require("devtools")) install.packages("devtools")
devtools::install_github("pvictor/topogRam")

Usage

You can use it like any other htmlwidget :

library("topogRam")
data(frRegPop)
topogRam(
  data = frRegPop,
  key_var = "P13_POP",
  geo_lab = "region",
  colors = c("#FEE0D2", "#FC9272", "#DE2D26")
)
