Work Description: shiavm006 opened a new pull request, #757:
URL: https://github.com/apache/mahout/pull/757
### Purpose of PR
Fix `draw_circuit()` method to return visualization string instead of None.
The method was printing the circuit visualization but returning `None`, which
contradicted the docstring that claimed it returns a visualization object. Now
all backends (Qiskit, Cirq, Amazon Braket) return the visualization string as
documented, allowing users to capture and use the return value.
