This map generator uses the Google GeoChart API. The output is very similar to
Travel Map Generator. The main
difference is that you can hover over the countries and get the names. Also, there is no limit to the size of the map. You can adjust the size by changing the w and h values in the embeddable code.
The color of the selected country is always Green. If you require different values for each country or a chart legend, use the
Google Code Playground.
Note: This map is not an image. It requires you to embed HTML code into your document.
