Leaflet map with total tax rate per municipality

[lambiase]

It would be nice to have a leaflet map showing the total tax rate for all the municipalities in Switzerland depending on:

• Civil status
• Number of kids (and their age?)
• Double income?
• Church affiliation
• Age?
• etc.

See for example:
https://blog.derbund.ch/datenblog/index.php/4117/wo-liegt-ihr-steuerparadies

The polygon information for the different municipalities can be downloaded from
https://opendata.swiss/en/dataset/swissboundaries3d-gemeindegrenzen
(see https://map.geo.admin.ch/?topic=swisstopo&lang=de&bgLayer=voidLayer&zoom=2&layers=ch.swisstopo.swissboundaries3d-gemeinde-flaeche.fill&catalogNodes=1476,1482&E=2662949.62&N=1169260.05 for a rendering of municipalities on the map of Switzerland)

The polygon data needs to be converted into a format that can be consumed by leaflet, for example geojson.
It might be useful to have a look at https://github.com/interactivethings/swiss-maps
