docs: Returns text containing a diagram describing the circuit.
  
          Args:
              use_unicode_characters: Determines if unicode characters are
                  allowed (as opposed to ascii-only diagrams).
              transpose: Arranges qubit wires vertically instead of horizontally.
              precision: Number of digits to display in text diagram
              qubit_order: Determines how qubits are ordered in the diagram.
  
          Returns:
              The text diagram.
