I'd like to create a Google Visualization API intensity/heat map based on UK counties.

To do this, it appears that I need to use a custom KML/KMZ file that contains the county mapping data (which I've located).

Could anyone provide me with a sample of how I can display an intensity map based on a KMZ file? I know how to display Google Visualization intensity maps in general. I just can't find any examples that use a custom KMZ file.
