British MEPs go NUTS

I know what you are thinking, the European Parliament has more than its fair share of nutcases but this is about NUTS as in Nomenclature des unités territoriales statistiques  which are defined across Europe, but we'll take the UK as a case study.

A year and a half ago I looked into grouping counties and unitary authorities together in Tableau to form the European election constituencies in England. This takes a fair amount of work, and I had a dodgy solution with dual axis to avoid having to also group all Scottish, Welsh and Northern Irish counties in a similar way.

A much simpler solution using the latest Tableau functionality is to use NUTS as geographic role. This avoids needing a source to define the constituencies at all, so the data source of the MEPs of each region is enough to also generate maps.
