📎 Some examples

Here is an example of how you could use the decorator.

from callviz import callviz

@callviz(_format="png", memoization=True, open_file=True)
def fib(n: int):
    if n < 2:
        return n

    return fib(n - 2) + fib(n - 1)

@callviz(show_link_value=False)
def rev(arr, new):
    if arr == []:
        return new

    return rev(arr[1:], [arr[0]] + new)

fib(7)
rev(list(range(6, 0, -1)), [])
