Gapminder is a helpful data-visualization website that enables you to analyze data trends spatially and temporally.

You can visualize a range of country data using a map, trend lines, or a ranking bar graph. For each option, you can watch an animation of change over time. The available data is broken down into categories such as economy, energy, environment, population, and society.

There are a many datasets embedded in the website that are very relevant to our discussions in class. One is water withdrawal (you can see it if you click on the map header and select environment > water > water withdrawal/person. I chose to compare South African and the United States over time (you can do this by pressing the play button on the bottom left corner of the data viewer). I was surprised to see how dramatically the USA has reduced its water consumption over time. This tool also helped me visualize the large gap between US water consumption and SA water consumption.
