Radar Chart Angular 16 Example

A radar chart, also known as a spider chart or web chart, is a graphical representation that displays data on a two-dimensional plane with multiple axes originating from a common center point. This type of chart is often used to visualize and compare the performance or characteristics of different categories across various quantitative variables. Each axis represents a specific data attribute, and the data points are plotted along these axes to form a shape resembling a spider’s web or a star.
