ZeeMaps now allows you to color and mark different regions of the world.
For example, you can easily create a map coloring all the countries you have visited.
We support coloring of states in Canada and the US, and all the world countries. In the future, we plan to add more states, and further divisions in the US, like zip code boundaries and counties. If you'd like to see particular region added, please send us a note or leave a comment on this blog.
To add a state, use the "Add->Region" menu item above your map. To update a region, click on it to bring up an update dialog. For both these, remember to be logged in as a moderator of the map.
The click on a region can be a bit slow, so please be patient.
Here's a map coloring the states won by Senators Clinton and Obama up to now in the Democratic Party's presidential primaries.
