Hello, Tommer

I primarily use exploratory data analysis (EDA) graphs to get a sense of relationship. If I am interested know the exact relationship/association for among any particular model then I use mathematical metrics.

You may like to refer to the correlation matrix discussed in my article. It is a crossbreed between graph and mathematical metrics.
