Hello Jerome, I am very happy to have found your blog. I would like to create a simple-looking map — a contiguous cartogram, or dorling cartogram, or graduated symbol map — showing value of exports from the San Francisco Bay Area to countries around the world. In concept, it is simple, but I am finding that the mapping software sites (for freeware downloads) quite complicated to interpret. Can you make any suggestions? Thank you. Sincerely, Sarah

Hi Sarah.
I don’t know of a software that could generate dorling cartograms. Coding them with protovis is not so difficult, if you have some knowledge of the library you can easily adapt existing programs such as this one with your geography (or have it done if you don’t want to code it yourself, I can give you names).
now to do a map instead of a cartogram – with, for instance, circles of various sizes laid upon countries. For this any mapping library would do, like google maps for instance. coding is still required though but there are tutorials to walk you through that.
finally there are a number of solutions to generate choropleth maps (ie maps where countries are of different colors) online such as google fusion tables
hope it helps
