RelationsInspector is a generic node-based editor for the Unity game engine. It’s free and open source and comes with a number of plugins. See the sidebar for more plugin information. It offers many customization options for writing plugins for your own use cases, but getting started is as easy as adding just two attributes to your code. You tell it what kinds of relations you are interested in and give it an object to inspect. The RelationsInspector then generates a graph and presents it to you.
