Software to create color coded maps from excel?

[Guest]

I'm looking for software that enables me to use my existing data in an excel
spreadsheet, and from excel launch an application that creates a thematic map
with zip codes that are color coded. There are a few I've found, but they
don't work straight from excel and/or I have to draw the zip codes manually.

I was able to find a product called The Town(tm). Has anyone heard of it?
They have a video of how it works online.
