I am surprised by the fact that Google Chart Generator is by far the most popular feature of my website. It makes sense, though, now that I think about it. It appeals to a much broader audience than everything else here. Google recently added a couple more chart types to its Google Chart API: Google-O-Meter and Maps. Therefore, in a shameless attempt to pander to the masses, I incorporated them into my Google Chart Generator.
Google-O-Meter creates charts similar to the familiar Speed-O-Meter (speedometer). Users can specify image size and image background color, dial color gradient, pointer position, and a pointer label. It’s simple, quick, and easy to use. Give it a try if you need to display a single point of data in relationship to its range.
Maps creates simple, yet elegant, charts of land areas, including Africa, Asia, Europe, Middle East, South America, USA, and the world. Users can highlight selected countries or states with any color along a user specified color gradient (scale). I see plenty of potential applications for Maps. Experiment with it; you may be surprised at how much you learn about geography.
