Boetti's map using D3
Due to their peculiar bounding boxes (see Jason Davies nice visualization) some countries need special treatment
- France: split Guyana and map French flag accordingly
- USA: map the flag separately to Contiguous USA and Alaska (given the scale probably ignoring all off-shore United States territories and possessions will not be visible)
- Kosovo: cope with its lack of UN code in order to plot the flag.
For these special cases we could:
- use a topojson file for the parts we are interested and replot mapping the relevant flag.
For USA: Alaska and Continental USA.
For France: Metropolitan France (i.e. includes Corsica) and Guiana
- add an entry for Kosovo (special iso code and flag entry)
