I was wondering if anyone has any advice on implementing a circular 'phylogenetic' type binary tree visualization using QTGraphics - the type of tree where the root is in the center and the branches circle around a set radius.

Something like this, except with the labels replaced with dots:

I could not find any pre-made widgets that were suited for this purpose.

I'm currently using the 'Elastic Nodes' setup as a template - which utilizes QTGraphicsScene and QTGraphicsView, and have managed to create a standard tree visualization with dynamically set distances:

But wanted to switch to a circular format like the image above, if possible.

Many thanks in advance.
