Bug in circuit library visualization function

[ElePT]

Environment

• Qiskit version: 2.0.0
• Python version:
• Operating system:

What is happening?

The circuit library docs show in many cases illegible circuits that come from _generate_circuit_library_visualization. For example:

How can we reproduce the issue?

        from qiskit.circuit.library import GRX
        from qiskit.visualization.library import _generate_circuit_library_visualization
        import numpy as np
        circuit = GRX(num_qubits=3, theta=np.pi/4)
        _generate_circuit_library_visualization(circuit)

Note that this is run inside a sphinx ..plot directive, not sure if the issue is limited to the docs rendering or also happens when run independently.

What should happen?

Circuit library visualizations should be readable.

Any suggestions?

I think this is a part of this issue: #13558
Perhaps we can close this issue and add this case as a comment there?
