I have a pandas dataframe df looking like this
   A     B    C
A  5%   95%  0%
B  10%  10%  80%
C  40%  20%  40%
(My real df has 22 rows and 22 columns).
My target is to have the best dataviz to show the datas of my dataframe.
I was thinking about this kind of graph (only about the style - I don't need, in my case - a triangular matrix).
Which tool/library could I use to obtain (visually) the same result ?
