Adding plotting script for ArborX query order

[aprokop]

Co-authored-by: Damien L-G dalg24@gmail.com

Not sure where to put it, so it's in scripts for now. I would like to carry it with the repo so it could be used anytime without access to Jupyter.

There are some quality of life improvements compared to original @dalg24's version:

• Command line arguments support
• Automatic calculation of the number of files to parse
• The ability to either display or save to a file

Right now, there is no test for it, but I could add it if considered useful. For example, I could add a test for visualization driver to dump data, and run the script just to make sure it runs.

I would have placed it in packages/Search/example/viz/ and added a requirements.txt that lists docopt, matplotlib, and numpy. No strong opinion on this though. I think it's good we finally start putting these scripts under version control. I just never was sure where would be most appropriate.

Note that now that #535 made it into master, it is trivial to implement a new visitor that output the matrix directly in the format you like instead of parsing the ones in DOT format.

I see it is still a draft but I'd like request that me or someone other than Andrey post in the conversation one image produced by the script before we accept theses changes.

For the record, in the dev/ci container I had to do apt install python3-pip and pip3 install -r requirements.txt

@dalg24 I assume that in the container one is able to run only saving to file, and not in display mode, correct?

I only saved the plot. In principle I think it is possible if you run your container with -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix or similar but I didn't try cause I connected remotely and do not really want to bother with X forwarding.
