Addition of new plots to the family of lets-plot LayerSpecs

[OSuwaidi]

Thanks for the wonderful work guys, this visualization library is superb!

Are you guys planning to expand the list of supported plots (LayerSpecs)? If so, could we suggest/vote on which additional plots we would like to be introduced to the library?

Charts like waterfall, parallel coordinates, and radar plots are all wonderful ideas!

Hi @OSuwaidi, yes absolutely, we appreciate suggestions that let us better understand needs of chart creators.

waterfall

The geometry itself looks like simplified crossbar. Would it have any default statistical transformation?

parallel coordinates

An interesting challenge. We can have it as a moonshot goal for now)

radar plots

Look cool! Could you create an issue?

That's awesome news!

Regarding the waterfall plot, it doesn't need a statistical "transformation" per se, rather it takes the difference operator on the y values while preserving the initial and final values as such:
x = [2020, 2021, 2022, 2023, 2024]
y = [100, 105, 102, 100, 105] -> y = [100, 5, -3, -2, 5, 105]
The key here is to highlight the changes in the y values as (colored) signed differences, relative (aligned) to the previous y value (or previous bar), and at the end, displaying the net value of those differences.

And I'll create an issue for the radar plot now.

Much appreciated!

Another plot idea gaining traction nowadays to consider supporting is what's called a Snakey diagram.

Thanx, added a feature request: #984

BTW, are you aware of this new book Coding for Economists?
It features lets-plot in many places and even contains an entire chapter about lets-plot: Easy Data Visualisation for Tidy Data with Lets-Plot.
