How do people plot scatter plots with a color bar provided two lists of data for the scatter plot and a third list for the colors?

something like this maybe: (plot (for/list ((data (in-list (list data1 data2))) (color (in-list colors))) (points (data->points data) #:color color ....)))

This part I understand, I was looking for how to add a colorbar, is there a built-in functionality to do that?
