Geo-visits

With Google Charts, it is easy to create small non-interactive maps with filled selected countries. For example, the countries I have visited so far.

Such map is created by making a URL with several parameters (e.g. which countries to fill or what colors to use). If you do not want to do it manually you can use a small JavaScript that reads your personalized list of countries to be colorized (which is also a JavaScript file) and creates the chart URL itself. See the source of the page above as an example.
