title: How to draw routes in open street maps using Python/R?
body: <p>I have data in the form of lattitude and longitude co-ordinates. I want to plot a route for those co-ordinates in OSM using either Python or R. Can somebody tell me where can I begin? I've not worked with OSM before.
  For each user I've a route which is a set of lattitude and longitude co-ordinates, so I want to plot each user's routes.I would prefer python alternatives over R.</p>
