I do agree that human-readable is probably better than using pi/sigma. These didn't mean anything to me when I started using Polars. But as @datenzauberai pointed out, there is a good reason these symbols are being used.

These are the symbols from relational algebra, that is taught in many computer science courses on relational databases. See https://en.wikipedia.org/wiki/Projection_(relational_algebra) and https://en.wikipedia.org/wiki/Selection_(relational_algebra)

I want to keep the output concise in the graphs. Would be cool if we could add a legend though.
