In a project on arcgis online, I have a map of the city of Rio de Janeiro divided by census tract, a form of division of Brazilian cities adopted by IBGE, the institute responsible for demographic research. Each census tract has a unique code. From the Shapefiles that generated the map, with Python and Pandas I generated a .CSV file, and to this file I added a column, called class, that assigns each census sector values from 1 to 7. How to differentiate census sectors in the map based on the class column?
