I'm currently working on an analysis of correlated variables involving +20 variables. I can create correlation (triangle) plots and that is quite helpful but I am wondering what other kinds of data visualization tools might exist for looking at correlations and biases in many variables. A reference to some Python libraries would also be quite useful.

I always find horizontal barcharts to be very informative when looking at how all variables are correlated to a single variable
