title: Tutorial for python radar chart/plot
body: <p>I want to do a radar plot in python but i don't know how to do it. I read some tutorials on the web and most of them are very complicated (drawing polygones, making calculations to place points, ...).</p>
  
  <p>So I wonder if someone have a "simple" tutorial on it. I don't want to do something very extraordinary, juste simple. Also if there is a python library which can do it. All the tutorials I read are using matplotlib, but it's quite difficult. I also find the library "pychardir" but I can't install it.</p>
