When trying to use the Filled Map visualisation power bi is not recognising all two digit ISO country codes.
A simple test to replicate this would be to use an execl sheet with 2 columns as a datasource. Column 1 the ISO county codes GB, FR and HU and Column 2 some random numeric values.
Use the Execl sheet data with with the filled map visualisation and select both columns as your fields.
You will notice that GB(Great Britain), FR(France) display properly but HU(Hungary) does not display on the map.
Not sure if this is a bug or by design? If anyone could advise that would be much appreciated?
