Data plotting examples

[ynadji]

I saw the recent activity on CSV parsing and seeing lisp-stat mentioned reminded me of how I was able to get vega-lite plots working in emacs from Common Lisp without a lot of effort. I've also noticed the plotting libraries from awesome-cl and it would be fitting to have some examples in the cl-cookbook for general data analysis through plotting workflows.

I'm interested in doing this work, but unsure of when I can/will get to it and wanted to make the issue before I forget about it :).
