viz=False does not work

[SamuelGabriel]

I don't really understand the visualizations tbh, so I wanted to turn them off, but viz=False, leads to the following error:

---------------------------------------------------------------------------
UnboundLocalError                         Traceback (most recent call last)

     43         print("Invalid Access:", failures)
     44         print("Yours:", z)

UnboundLocalError: local variable 'failures' referenced before assignment

changing the test code a bit to something like this in the relevant lines worked for me:

failures=None
if viz:
    failures = triton_viz.launch()
if not match or failures:
    if failures:
        print("Invalid Access:", failures)

Can you let us know what is unclear about the visualizations? I think that would be useful for us.
