Radar Chart, also known as Spider Chart or Star Chart, is a chart used to display multivariate data on a two-dimensional graph. The structure of a radar chart is similar to a spider web, with multiple axes radiating out from a central point, each axis representing a variable. Variable values are represented by points on an axis, and lines are used to connect these points, forming a polygon.
