Error with Graph Tree Layout example in the graph.py about manim

[uwezi]

The code from the example scene works fine in the current version 0.18.1 - this can also be checked with the interactive rendering from within the documentation.

Quick Fix

Using directly the root_vertex param instead of using the layout_config param works just fine.
I suggest revisit the examples in the code and check if some of them are deprecated.

from manim import *
class TreeLayout(Scene):
    def construct(self):
        graph = Graph(
            [1, 2, 3, 4, 5, 6, 7],
            [(1, 2), (1, 3), (2, 4), (2, 5), (3, 6), (3, 7)],
            layout="tree",
            root_vertex=1,
            labels=True
        )
        self.add(graph)

@dalopezt Which version of Manim are you using? Make sure it is the same version as the documentation you are reading. Graph layouts were redone in v0.18.1 so if your version of Manim is older you should look at the older documentation.
