This seems related to to rstudio/bookdown#15 but I haven't been able to figure pin it down. The example is here but the offending code is
p2 <- ggplot(mtcars, aes(x = disp, y = mpg)) +
geom_point_interactive(aes(tooltip = car))
ggiraph(code = print(p2))
and my bookdown.yml has new_session: yes. Other htmlwidgets do work.
```r
p2 <- ggplot(mtcars, aes(x = disp, y = mpg)) +
geom_point_interactive(aes(tooltip = car))
ggiraph(code = print(p2))
```

You were correct that this was related to rstudio/bookdown#15. The root cause is that ggiraph uses the temporary directory to create the HTML dependency for the widget, and R will clean up the temporary directory on exit. Since you used new_session: yes, the Rmd is compiled in a separate R session; your HTML widget is created there but actually rendered later (after that R session has quit). By the time it is to be rendered, the temporary directory has gone.
Therefore you have to choose between using ggiraph and new_session: yes. You cannot have both.
