Consider adding regex or wildcard specification of variables in Plot.pair

[mwaskom]

e.g.

Plot(penguins, y="body_mass_g").pair(x="bill_")

or

Plot(penguins, y="body_mass_g").pair(x=".+_mm$")

One question: regex matching or some simpler glob-style wildcard matching, perhaps with a negation operator? (e.g. x=!bill_*")

Regex is more flexible but trickier to work with for some common applications in this application (i.e., anti-match on a common prefix). Regex is maybe marginally less familiar to people, but still probably the way to go.

For what it's worth I've had to make similar charts (usually scatter matrices) where I had to drop some columns like ID, dates so a built-in 'negation' will be helpful.

Also, even if regex is overall less familiar to people it is a standard known syntax (with many debug resources) which should simplify adoption in long term.
