I’ve been told that it’s quite easy to create your own maps for PowerGadgets, and I plan to give it a try some time soon.
If you’re in the US, it’s already very easy to throw together a map of the US which charts the states that have had sales. And in the Advanced Properties window you can add conditional formatting very easily to change the colour according to the range. Easy to script for PowerShell commands too. Of course, if you’re not in the US, then you may want to make your own custom map to show where things are.
It would be nice to have a gadget that showed where your company was making sales were made by Australian postcode. Or make a map which shows the office plan of a call-centre with the number of calls made that day.
