Info Windows for Google Maps (from Fusion Tables)

A slightly boring technical post today because from time to time people get in touch to ask technical questions. So, I thought I'd just share a bit of my (limited) knowledge on controlling what appears in a google map info window when you click a map layer using Fusion Tables. Most of this probably applies to non-Fusion Table maps as well. Here's what I'm talking about...

Link directly to this page here.

As you can see from the screenshot above, this info window has a chart (drawn from the Fusion Table which is mapped) an image (a map key) and some text, which also pulls out unique data for each area on the map when you click on it. Since Fusion Tables are relatively new, there isn't an awful lot of information out there on how to do this (at least not info that simpletons like me can understand) so I spent quite a bit of time experimenting with the code behind the info windows. There is some useful information on this page and the pages it links to but when you have your own dataset it can be a bit difficult to grasp.

Not much else to say except that I've copied an image below which shows the code and the info window side by side. If you click on the image it should take you to a PowerPoint file which you can then use to copy the code if you wish. I'm certainly no expert but someone may find this useful!
