1 - Polars has support for plotting in the most recent release. Using Matplotlib w/ Polars data tends to work too. Otherwise, you can drop into Pandas to get support where it may be missing. 2 - If you just want the columns, there is no need to make an expression; just pass the string. There are shortcuts like pl.sum(col) instead of pl.col(col).sum(). I guess you could shortcut, c = pl.col, if you really hate typing it... 3 - Polars supports chaining and encourages it out of the box. Anything specific you are looking for?
