The visualizations from the :func:`~.plot_gate_map`, :func:`~.plot_coupling_map`.
|
|
:func:`~.plot_error_map`, and :func:`~.plot_circuit_layout` functions have been significantly
|
|
improved for rendering layouts of backends with large numbers of qubits. This was accomplished
|
|
by leveraging `graphviz <https://graphviz.org/>`__ through rustworkx's ``graphviz_draw()`` function
|
|
to perform a more sophisticated algorithmic graph layout that scales for large numbers of
|
|
qubits.

upgrade:

- |
|
|
The visualization functions: :func:`~.plot_gate_map`, :func:`~.plot_coupling_map`.
|
|
:func:`~.plot_error_map`, and :func:`~.plot_circuit_layout` now depend on
|
|
`graphviz <https://graphviz.org/>`__ being installed to function. This change was
|
|
necessary to enable visualizing backends with larger numbers of qubits. This
|
|
additional external requirement is in addition to the existing optional dependencies
|
|
these functions previously required. You find details on how to install
|
