What shape does a radar chart resemble?

A radar chart resembles a spider web due to its unique structure of multiple axes that radiate from a central point. Each axis represents a different variable or category, which gives it a geometric shape reminiscent of a web. The values for each category are plotted along these axes and interconnected, creating a polygonal shape that can vary in complexity depending on the number of variables.

In contrast, the other shapes mentioned—such as a bar graph, pie chart, and line graph—have distinct formats that do not share this radial characteristic. A bar graph uses rectangular bars to represent data amounts, a pie chart displays proportional slices of a whole in a circular format, and a line graph connects data points with lines to show trends over time or categories. Each of these differs fundamentally from the interconnected, radial layout of a radar chart.
