Free mapping tools?

[#1]

I'm wondering if anyone can point me in the direction of some free, or very cheap mappings tools/instructions.  All I really want is a heat map of the US, with the ability to qlik the most impacted areas based on current selections.

There is a Mapping Tool called SVG Map

Here is a link to it
