This example shows different attributes that you can associate with nodes in a graph.
Since no explicit positions are passed for the nodes, Rerun will layout the graph automatically.

DESCRIPTION = """
# Graphs
This example shows various graph visualizations that you can create using Rerun.
In this example, the node positions—and therefore the graph layout—are computed by Rerun internally using a force-based layout algorithm.
You can modify how these graphs look by changing the parameters of the force-based layout algorithm in the selection panel.
The full source code for this example is available
[on GitHub](https://github.com/rerun-io/rerun/blob/latest/examples/python/graphs?speculative-link).
