Explanation

Radar charts (also known as spider charts, polar charts, web charts, or star plots) are a way to visualize multivariate data. They are used to plot one or more groups of values over multiple common variables. Radar Charts are used to compare two or more items or groups on various features or characteristics. Example: Compare two anti-depressant drugs on features such as efficacy for severe depression, the prevalence of specific side effects, interaction with alcohol, a continuation of relief over time, the cost to the consumer, etc.
