Circles In Legend For Leaflet Map With Addcirclemarkers In R - Without Shiny

I am creating a leaflet map in R - I don't need to build a shiny app, and haven't tackled that particular skill set yet! I was trying to follow along with this post here to create

Solution 1:

From the original answer, you omitted one set of global style definition that is responsible for the round shape.

Add border-radius: 50%; to the colorAdditions set of css styles, which is the one style you are needing from it.

This would make:

  colorAdditions <- paste0(colors, "; border-radius: 50%; width:", sizes, "px; height:", sizes, "px")

A bit hacky, but works.
