I am brand new to Graphhopper trying to understand the basics.
I noticed that the sample android app uses MapBox service to get map for display. My questions:
- Do we always need such service as MapBox or does Graphhopper service itself provide map for display? If it does, how?
- If we must use services such as MapBox, is there alternative open source and self-hostable map service that is recommended for use with Graphhopper?
