A small look at the 2018 Brazilian election, joining the electoral zones with graphical information from IBGE. Not a currently maintained repository, but maybe the code could be usefull to somenone :)
The address of the various electoral zones were manually acquired as CSV files from the oficial tse website
The result of the elections for each electoral zone was acquired from the "Presidente (formato ZIP) " file also in the oficial tse website
Using Google's Geolocation API the numerous address were processed as latitude and longitude.
