radar chart (at most 3, to add more)

Introduction
A radar chart is a multidimensional data visualization tool that radiates multiple axes from a central point, with each axis representing an indicator. By connecting the values of each indicator to form a polygon, it allows for intuitive comparison of the overall performance and strengths and weaknesses of multiple objects across different dimensions. It is commonly used for effectiveness evaluation and comparative analysis.
