I am optimizing and testing a new QtWidget I have created for force directed graph layouts. Currently it will only utilize the CPU but I am working on a CUDA implementation as well. When release the widget will allow developers to place force directed graph layouts in their qt applications. Additionally this will be included in a new version of inav hopefully out soon.
