Gapminder is a tool that allows the user to present a huge amount of world data visually in the form of moving, interactive graphs.Gapminder takes a stream of data dependent on time, and presents it visually, in the form of moving graphs. The strength of this tool is the data it gives access to. a staggering amount of worldwide data, from geographical disasters and national economy, to personal poverty and AIDS.
The data covered in Gapminder is worldwide. The data is displayed on a graph, with variables shown on the x-axis and y-axis with size and colour variations to depict magnitude and categories. The graph can compare multiple sets of data at one time, over a period of years which facilitates easy comparison. Sections of a graph can be zoomed in on, and the path of individual points can be followed, to emphasize specific data when needed. The Gapminder data can even be displayed over a map, so that statistical changes can be shown geographically.
Some of the projects undertaken by Gapminder are described below.
