I often avoid these sort of visual methods, because:<p>- they only work with 2 variables, but many interesting problems require digging into more variables<p>- they only work with medium-sized numbers, and aren&#x27;t readable when P&lt;0.01 or P&gt;0.99<p>So they&#x27;re great for gaining intuition (like the Simpson&#x27;s Paradox example), but when you try to solve a real problem you find yourself boxed in.
