      Create a simple chatbot using Python and state diagrams. The chatbot has multiple states defined as dictionaries,
      each containing a message and possible replies that lead to other states. The conversation starts from 'state0'
      and continues based on user input until a terminal state is reached.
  
      Example:
      for create_chatbot_with_state_diagrams() == ['Hello! How can I help you?', 'I need some advice', 'Sure, what kind of advice do you need?', 'Career advice', 'It is always a good idea to research the field you are interested in and creating a plan to learn the skills that are required. Make sure to contact professionals in the field to understand their experience.', 'Goodbye!']
