For more details, see the rayshader package website. There are other great posts by Tyler like doing 3D ggplot charts and 3D maps with rayshader. Please note - like anything cutting edge - this package may have bugs and dependencies that require you to set up the right tools. So only pursue if you’re up for the challenge.
