How to create a hexagon skills graph with Unity UI?

Hi there,

I'm fighting a bit trying to come up with a proper way to create a hexagon-shaped graph that would show the player skills/attributes and be modified depending on their value. Let me show you a quick mockup of what I'm seeking:

(Just made up those stats, but you get what I mean) Now, how could I achieve something like that? The way this works is simple, if the player tweaks a given skill, its 'vertex' of the green 'star' goes higher or lower depending on the skill's value.

Initially, I tried to create something like this in the form of some sort of ProgressBar, but to no avail. Is there a way to set up that kind of menu using Unity's UI tools?

Thanks in advance.
