 ### Added
 - Added logic to `bump-version.yml` workflow that automatically updates `CITATION.cff` upon new release ([#147](https://github.com/qBraid/pyqasm/pull/147))
+- Added `pyqasm.draw()` function that draws quantum circuit ([#122](https://github.com/qBraid/pyqasm/pull/122)):
+
+```python
+from pyqasm import draw
+
+qasm = """
+OPENQASM 3.0;
+include "stdgates.inc";
+
+qubit[3] q;
+bit[3] b;
+
+h q[0];
+z q[1];
+rz(pi/1.1) q[0];
+cx q[0], q[1];
+swap q[0], q[1];
+ccx q[0], q[1], q[2];
+b = measure q;
+"""
+
+draw(qasm, output='mpl')
+```

+
+\- Currently, only the `mpl` (matplotlib) output format is supported.
+
+\- Use `draw(..., idle_wires=False)` to draw circuit without empty qubit/classical bit registers.
+
+\- Save the visualization to a file by specifying `output='mpl'` and a `filename`:
+  ```python
+  draw(..., output='mpl', filename='/path/to/circuit.png')
+  ```
+
+\- The draw method accepts either a `str` (QASM source) or a `QasmModule`. The following are equivalent:
+
+```python
+from pyqasm import loads, draw
+from pyqasm.printer import mpl_draw
+
+module = loads(qasm_str)
+
+draw(module, output='mpl')
+draw(qasm_str, output='mpl')
+
+draw(module)
+draw(qasm_str)
+```
