There is an implementation of Chernoff faces where a fish is used instead of a human face, so it is called Chernoff fish:

It is implemented in D3 and React and the source code is here:

I implemented my own version long ago (for MS-DOS) and I am quite surprised that there is still some interest in the topic.
