How to use ggplot to construct long-awaited Radar Map in R language Visualization
In this issue, the editor will bring you about how to use ggplot to construct the long-awaited radar map in R language visualization. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

I tried to simulate the radar chart with line chart + polar coordinates (this is what I did before when making pie chart, circle chart and rose chart).
The result is a thick line with the following nondescript graphics:
