Wow nice, it's based on ggplot2-like grammar-of-graphics language. See examples here: https://lets-plot.org/pages/charts.html

The data plots look pretty nice: https://lets-plot.org/pages/charts.html#discrete-icon-discre...

And so do the distribution plots: https://lets-plot.org/pages/charts.html#visualization-of-dis...

How does this project compare to `plotnine`, which is the ggplot2-like plotting library in Python?

Is ggplot2 generic enough that it allows one to create any graph one wants, or is it opinionated in how or what graphs can be made?

However the best thing about this library may be that it is available for Kotlin.

What? How's that? It's written in python. Does kotlin have python interop?

It's linked in the description

Ggplot is opinionated, but mostly in its api.

From memory the only thing you can’t do in base ggplot is have to y-axis, but there are plenty of libraries available that expands the types of plots available (eg gggraph for plotting network graphs)

You can’t have two y axes? I’d call that a pretty strong opinion.

This isn’t the case

Well, the thing is you can have two y axes, but they must be simple transformations one another. The reason being (iirc, don't want to put words into Hadley Wickham's mouth) is that if you cannot provide a transformation from one y axis to the other, then the data shouldn't be in one plot to begin with (as it then shows clearly distinct data).
