Create a .twbx Tableau workbook which includes the shapefiles of Uganda, Kenya, Tanzania, South-Sudan and Rwanda, up to county level (= district level).
We should be able then to add data source in the workbook and use the "filled map" option of Tableau to create worksheet.
A merged shapefile for the 5 countries with the latest administrative divisions (level 2) is available here.
The quality of the file may require a check and a simplification of shapes if it's too heavy.
The [login to view URL] file should be used as data source to test the inclusion of the shapefile as custom geocoding.
We should be able to display the "sale volume" (column "sale") of each district (county) using the "filled map" option of Tableau.
