Investigate GeoTools as a plausible solution

Look into the API of GeoTools and determine whether this is a good way of implementing map features visualizing data from DHIS. We should figure out in GeoTools roughly the code involved to render a map similar to that of the current interactive version in DHIS (which uses google maps). Having a good basis map with critical information such as town names and roads is a good cue to those viewing the information. After a good basis map layer can be rendered, then rendering of DHIS data remains, be it dots, circles, colored polygons.
