A Brief Introduction of the Spider Chart

The spider chart, also called radar chart, web chart, polar chart, and star plots, is named by its special appearance. It is a chart that uses two dimensional graph to display multi-dimensional data structure. However, it has an extreme limit which more than 2 but no more than 6 items can be judged, otherwise you cannot see the data clearly. Thus, we should explore when the proper occasions of using this chart are.
