In this modern era outlined by the rising dominance of graphical representations of data, the popularity of a wide assortment of charts has soared to considerable heights. One such graphical form of data that lets users depict the comparison of the characteristics of several data groups and entities that have distinct features is Radar Chart.

Owing to their shape, the charts are popularly known as spider web charts, polar charts, star plots, and web charts.
The values for the data are mapped on these spokes and connected to create a polygon. Hence, a radar chart shows similarities, differences, and outliers for the services, products, and other items of interest at a glance.
