it's "visualizer: graphic" in the available elements list 
Are you sure?
To me that seems to be the build-in visualiser, and it looks nothing like your screenshot, or the screenshots from the plugin page?

I now get it.
I'm not sure it could literally be called a plugin, but it is some set of pre-defined visualisations that can be selected (and modified) when using the build-in visualiser?
It would be good if the creator (raul) explained that on his plugins page.
I am guessing there are not many users that are using it because how to use it is neither obvious, nor explained.

I've added it to the table in the start post with some additional comment.
Thanks boroda for making me (us?) aware of it.
