The Visualizer, shown in Figure 1, provides a user-friendly method of generating histograms, line plots, bar charts, and scatter plots for each of the datasets. It provides basic filters and categories for viewing the data and the ability to download charts in PNG format. The Visualizer does not require any special skills and is a good place to start for students without prior programming experience.

The CORGIS project also includes an Explorer for exploring the structure of each dataset. The hierarchy of the data is exposed via a series of chained windows. For example, clicking on a field in a map may open a new window for the a map of the referenced field.
