Currently, CircuitWidget.from_stim can be used to accept deltakit.circuit.Circuit objects indirectly (i.e. convert the Deltakit circuit to Stim circuit first), but it would be convenient to add the option for CircuitWidget to have a way of accepting Deltakit circuits directly. Thanks for considering it!
