circuit_graph.draw() TypeError

[ninja-lab]

All the examples for drawing circuit_graphs are throwing an error. Using lcapy 1.24

cct = Circuit("""

Hmmm, it works for me. It seems to be a problem with networkx. Which version do you have installed?

[ninja-lab]

I have networkx 3.3, with python 3.12.4. What about you?

[mph-]

I have networkx 3.1

I can't install 3.3 from pypi. Can you try networkx 3.1 to confirm the source of the problem?

[ninja-lab]

Confirmed, I just installed networkx 3.1 and now the circuit graphs all draw as expected.
