add a visualize parm for the ask function

Sometimes we don't need visualize the data. And by saving the token usage when we are testing some question, it's wise to close the visualize the data.

The error message you're seeing is due to the use of the list type hint in Python 3.8. The list type hint was introduced in Python 3.9, so it's not available in Python 3.8.

In Python 3.8, you should use List from the typing module instead. Here's how you can modify your code:

from typing import List

class VannaBase(ABC):
   # ...
   def generate_questions(self, **kwargs) -> List[str]:
       pass
