In Tropical Manipulation, I need to display the share of customers that each player will receive, and communicate the price interaction mechanics (a lower price gets more customers, etc). For this I've created a pie graph/chart material, so that I can add an image widget and use it in UMG.

To use it, download the .uasset file here and put it somewhere in your project's content directory. You can create a material instance from it and edit most settings, but you'll get more value opening it up and taking a look at how it all runs.
Feel free to use this in all your projects. An attribution/link-back is much appreciated but not required.
