From the spider chart demo:

Spider charts differ from radar chart in that a spider chart is a chart that has N "y" axes while radar chart has only one "y" axis, all radiating from a central point, where each "y" axis represents a specific category. For example, there are 5 "y" axes: GDP, area, population, inflation and growth here.

The radar chart, however, instead of being drawn in a typical linear X/Y space, the radar chart is drawn using a circular plot, with specific X values being shown using an arbitrary number of spokes drawn from a center point. These charts are useful for showing data over a cyclical set of values (for instance, hours of a day, minutes in an hour, etc.). With a radar chart, data is plotted in much the same way as with a typical line or area chart.

Actually, the radar chart is somewhat similar with line chart, the major difference between them is: line chart has a "straight" X axis while radar chart has a "circular" X axis, and the orientation of their Y axis is opposite.
