I have a dataframe that contains the spatial coordinates of polygons as columns x,y, their ID as a column and another column according tho whose values I would like to color the surfaces. Do you have suggestions on how to approach this? In R this is quite straightforward, but I already fail in plotting surfaces by using XY coordinates in Julia.
using Plots; plot([Shape(df.x, df.y)], group=df.ID,fill_z=df.value)
This plots arbitrary shapes that are stored in a dataframe with x,y,ID,value columns.
