The map shows the first and second round results for the presidential elections in france. When the mouse pointer is over a department, the results for it appear in a tooltip. At the moment of the creation, only the first round was done, and the second round data will be added this Sunday after the results are published.
The map is created using the geoConicConformalFrance projection of the d3-composite-projections library.
