How to create a graph from OSM data?
Osm2po will give you ready to use graph from osm data as sql script file, all you have to do is load it into database via psql -f command. In this table every single record is edge. Every edge has 2 vertices source and target – coordinations of this points are in column x1,y2 and x2,y2.
What kind of data is in OpenStreetMap map?
OpenStreetMap (OSM) is a global collaborative (crowd-sourced) dataset and project that aims at creating a free editable map of the world containing a lot of information about our environment. It contains data for example about streets, buildings, different services, and landuse to mention a few. You can view the map at www.openstreetmap.org.

What can you do with the osmnx package?
The osmnx package represents routes as a networkx graph – so we can do graphy things with it, like finding the shortest distance between two points, aka route planning: The route can also be plotted on an interactive map.
Can you use osmnx for GPS data points?
If you can do that for all your GPS data points, you will have the most appropriate OSM node/ point on the OSM road network (depending on how sophisticated your map-matching algorithm is) for each of your GPS data points. OSMnx has a very coarse map-matching representation in terms of getting the nearest node for a given (lat,long) in the form of
How to plot a route on a given map in osmnx?
OSMnx has a very coarse map-matching representation in terms of getting the nearest node for a given (lat,long) in the form of as mentioned by Geoff in his answer. You may choose to do this for all your GPS data points instead of just the end points and retrieving the shortest route.
How to save an OSM file as a CSV?
Load your osm file to some gis software, edit it (keep only what you really need) and then save it as csv. I thing you are talking about mapserver when you refer to a map file, if so, just call your csv from the DATA tag.
