I have made a video of a data set that I came across this morning. Unfortunately the data are not mine to give away so please go to the websites you will see in the video and download them free of charge from there.

The purpose of the video is to demonstrate just how easy it is with a table of data that contains geographical information to create a map that shows the spread of the data. Here are some screenshots from the video:

Firstly, the raw data after I have cleaned it a little

Secondly, the 3D map that Power Map creates, together with two series shown as columns or bars.usa_guns_2

The video is only 2 minutes 50 seconds long and if you are looking for inspiration on how to communicate data with a geographical aspect to it, watch this video!
