Looks cool! When I try this, I see the folloing error in the browser:

An error occurred while rendering. Rendering has stopped.

What did you do?

[edzer]

Thank you. Copy and paste without thinking ;-)

[edzer]

library(mapview)
library(cesium)
library(geojsonsf)

## standard data sets
fran = geojsonsf::sf_geojson(mapview::franconia)
cesium(data = fran)

leads to the following error in the browser:

When I run @edzer's code, I get the following error in RStudio viewer:

Furthermore, there's only a black screen when opening the .html in Chrome. In Edge, it works like a charm.

In chrome on windows I get:

In RStudio viewer it renders but is flickering constantly...

[edzer]

For me, it works fine in rstudio.

[tim-salabim]

On linux it works fine for me in both RStudio and Firefox
