We are looking for polygon data of Swiss regions (cantons). If you know a creative solution that does not require polygon data, that is fine too.
The standard Tableau map of Swiss regions does not satisfy us. The reason is that our regions data contains individual regions, merged regions, and a country.
Specifically we need polygon data of these regions, one custom region per line:
2. appenzell (two cantons merged into one region)
3. basel (two cantons merged into one region)
10. liechtenstein (not a swiss canton, but a country)
13. nid- & obwalden (two cantons merged into one region)
17. st gallen
Our goal is to display these regions coloured by some measure like sales.
The polygon data should be of the format that is supported by Tableau. We believe these columns need to be present: polygon id, point order, latitude, longitude, region name.
Please note if you know a way to achieve our goal without using custom polygon data we are happy too. (We have looked into custom geocoding but it looks like it will not be possible.)
