| Every visualization here is native (plain matplotlib/numpy) -- no Qiskit
|

|
| (dashboard_core.circuit_diagram); histogram/Q-sphere/Bloch spheres are
|
| now native too (dashboard_core.state_visuals), replacing
|
| qiskit.visualization.{plot_histogram, plot_state_qsphere,

| plot_bloch_multivector} -- the last Qiskit call sites this dashboard had.
|
| Qiskit's macOS instability was never proven scoped to just
|
| QuantumCircuit (see circuit_diagram.py's own docstring), so making these
|
| three merely "optional" instead of actually removing Qiskit would have
|
| left the same open question for a different set of functions; there's no
|
| reason left to keep it as a dependency here at all.
