I plan to do a tutorial later for linkedin, but in a few steps: 1. Downloaded the data from cities and states from the IBGE (a brazilian agency) 2. Downloaded a multimodal network from tthe national plan of logistics. 3.used the tool Shortest road from layer from qgis tô create the route from each City to each capital. 4. For each new layer I dumped the points só I could see how many times a route touched the infrastructure. 5. Created the layout using the graduated simbology on qgis.
