Rendering graphs in GUI with graphviz

I am trying to display a graph with graphviz. I have managed to display the graph by generating files.

Now I want to display the graph in GUI with pyQT or any other GUI manager. I am thinking about animating the graph for example color the nodes while using DFS or BFS algorithm.

What I have found on the internet:

• I have tried networkx with matplotlib but the display was a mess.

• I have thought about generating images and then render them in GUI but this consumes a lot of time.

• I have find python-igraph but it can not be customized like graphviz and I think it don't work with gui either.

So what should I do?

I am only going to use this lib in a school project so I don't want to draw the nodes by myself because it will take me some time. If there is an easy method to use the position given by graphviz I don't mind using it but plz give me some hints.

By the way, If you know any other lib i can use, please tell me.

Note: I need to display a graph in GUI and render it in real time.
