Add fold-like parameter to break long circuit diagrams onto next line (like Qiskit) #1718
Description
Currently, plot_circuit draws quantum circuits as one long horizontal line, which is challenging for visualization on websites and leads to poor readability, especially on smaller or variable screen sizes. Similar to how the line-wrap parameter wraps text diagrams by character count, it would be very beneficial to have a new parameter in plot_circuit for matplotlib figures that breaks long circuit diagrams onto multiple rows in the image, improving clarity and adaptability.
What I would want
In Qiskit, matplotlib circuit diagrams automatically break onto next lines (see attached image), greatly improving readability.
In Qibo, the same circuit appears as a long horizontal image, as in the below image.
Adding a parameter to plot_circuit to allow user-specified line breaks (based on gate count, circuit depth, or qubit count) would solve this problem.
