let's add tickFormat for human-readable days of week

and some way to solve the overplotting: opacity, binning on Y or distribution like violin plots

UPD 2025-12-01 second round: cool, now let's make it so that the days aren't skipping. for me it shows every other day of week (super easy fix with one line)

yes, that's it

would prefer to see solutions for overplotting and a way to compare different flavors and sizes

this good!
