Polygon maps are created by giving Tableau the coordinates of the shape we want to draw, and then connecting the dots by drawing a path between them. We have created a map with custom territories – provinces—by giving Tableau the exact coordinates (longitude and latitude) of their borders, which were contained in the Serbia_Provinces_Points.csv dataset. The Point order dimension notifies Tableau in which order to connect the dots (coordinate points). Finally, placing Province in Detail completed our map.
