  cirq-web doesn't support LineQubit
  ```python
  import cirq
  import cirq_web
  
  cirq_circuit = cirq.Circuit(cirq.H(cirq.LineQubit(0)))
  cirq_web.Circuit3D(cirq_circuit).generate_html_file(
      file_name="circuit_viewer.html",
      open_in_browser=True,
  )
  ```
  
  results in
  
  ```
  AttributeError: 'LineQubit' object has no attribute 'row'
  ```
