Telegraph Map

The telegraph map is the precursor to modern weather maps. The telegraph was the first way that weather was reported through electric means. It led the way for more advanced forms of electronically reporting and forecasting weather.

T-O Map

T-O maps were created during the Middle Ages. At the center of the map was Jerusalem, which was because it was heavily based upon religion. It was presented in a spherical shape, and only included three continents.

Star Plot

Star Plots display within each figure, one variable per line. The length of the lines are equal to the value of that variable.

Correlation Matrix

The Correlation Matrix is a map that represents the correlations between itself and each variable, for each pair. The solid diagonal always consists of ones.

Box Plot

Box plots are graphic representations of statistical information. Each box represents its own data, and can be compared. The line in the center of each box is representative of a median value. The whiskered lines running vertically represent the minimum and maximum values for the data represented in the box.
