   So this is something doable, but I'd say it required some advanced drupal chops and a few prior geo/mapping skills to know what each module does and how they work with each other. I have done this kinda thing since Drupal 6 and it still took me a few weeks of work to go from a few CSVs to a beautiful map with facets, per type styled polygons/points with nice labels, clustering, infowindows...
