PROCEDURAL GENERATION
Layouts can be created in the editor using the tools provided by the RadialLayout inspector, or procedurally via scripts.
The package comes with a full example of a layout created procedurally, you can find it in the Examples/ProceduralGeneration folder
See the RadialLayoutFactory component page for more info about using the Factory class to generate layouts.
If you don't want to use the Factory class, you can still easily generate a layout procedurally by setting the public properties of the RadialLayout component dynamically in your scripts and by calling the AddNode() methods.
Call Rebuild() when finished and the layout will be generated with your parameters.
