Display a graph generated by Graphviz in tkinter python

Question

I wonder if there is a package or example that display graphs that are created by Graphviz using PyGraphviz, in tkinter

My investigation:

My graphs can be rendered in to images without a problem. In the documentation of Graphviz, under Output Formats I see that it is also capable to output as tk. It is descried as text-based Tcl/Tk graphics primitives. When I try setting the format in tk and render, it generates a .gv file and a .tk file. The .gv file simply saves the source in dot language. The .tk saves as something very similar to tkinter canvas methods.

Code:

graph = ... #some graph source
graph.format = 'tk'
graph.render()

.tk file looks like:

Questions:

1. How would a graph generated by graphviz usually be displayed in tkinter?

2. Do I read and translate the .tk file to call corresponding methods in order for tkinter canvas to show the graph? Is that how it is meant to be done?

3. Is it better off just display the generated image file (svg,png,bmp,jpeg)?

4. Is there a way to do it without saving and reading files?
