Not documented how geojson node- and edgefiles have to be structured

[nicolasbeglinger]

Hello :)
First of all, thank you for sharing this package!
I'd like to read in a street multiline string into the "read_geofiles()" method. However, I didn't find any documentation on how to structure the multiline- and the corresponding point-layer (with the nodes). It always gets stuck with a key error "KeyError: "None of ['id'] are in the columns""

Is there any documentation that I didn't catch?
Cheers
Nicolas

Took me some time to figure it out too.

Your nodes file needs to have a column that uniquely identifies each node (commonly id).

Your edges file needs to have two columns:

• one that refers to the starting node id of the edge (commonly u)
• one that refers to the ending node id of the edge (commonly v)

Additionaly, I didn't find a method to transform a road/line/edges geofile/gdf into the required edges and nodes formats/files/gdf. So if you're starting off with a simple lines file, you will need to do the transformation yourself.
