I tried to recreate a map from C Sievert's great book on plotly & co (chapter 4.1.1).
Here the link.
library(plotly) plot_mapbox(maps::canada.cities) %>% add_markers( x = ~long, y = ~lat, size = ~pop, color = ~country.etc, colors = "Accent", text = ~paste(name, pop), hoverinfo = "text" )
The example runs as expected when using his RStudio Cloud version which loads plotly 220.127.116.1100.
If I update the package to the latest CRAN version (which I use on my machine, 4.9.2) the example doesn't work as intended. The result only shows the dots, but no map.
Any idea how to rectify this? Many thanks!
