[matplotlib-devel] Heatmap for 7K X 7K matrix

*Sending again after joining list*

Hi matplotlib users,

I am trying to generate a fairly huge heatmap of a 7000 X 7000. This is a
2D matrix in which each cell i,j have a similarity score between ith and
jth label.

PFA my first attempt (code - [0]).

Now I am looking for better visualization which can also tell me more
about *cell
level information*. To start with can I create a higher resolution image
such that I have at least 2X2 pixel for every cell. Resultant should be of
resolution 14000 X 14000

Are there more features like- By some user interaction can I know what pair
it represent? and what's the similarity score?
