Question: Taking a personality quiz on FiveThirtyEight, there were these graphs, consisting of a regular pentagon and an irregular pentagon inside with the points further from the center being lesser and points closer to the edge being greater, on top of regularly spaced bars:

I've seen this type of graph in other places. For example, on the website for the video game ARMS:

I was trying to think of a word for this, and couldn't. **What are these called?**

Answer: 
Polygon-circle graph
====================

This kind of graph is called a ‘polygon-circle graph’, according to [this Wikipedia article](https://en.wikipedia.org/wiki/Polygon-circle_graph).
It is just a plot of a point in five-dimensional space. The outer pentagon represents the first orthant in a five-dimensional space, or the convex hull of possible scores to the personality quiz.
