I'm having trouble uploading a .json file that contains polylines from the city of Rio de Janeiro within the Google Maps API.
I want to apply these route polylines between cities in Rio de Janeiro, on top of a google maps, but I do not know exactly how I will do this procedure. I have already loaded the Data Layer with GeoJSON from the layer.json file.
How should I do it? Here is the file "graph.json" for me to load.

This file represents a layer on the map with the municipalities of the state of Rio de Janeiro. But on top of this layer, I need to load a file called graph.json that contains the routes through the polylines demarcated in that file. But I have no idea more or less how to load this ".json" with polyline.
