I was recently looking into ggiraph (https://cran.r-project.org/web/packages/ggiraph/vignettes/gg...) for converting ggplot2 to d3 since it keeps most of the same syntax as normal ggplot2 charts.

However, looking at the output of these plot.ly charts may make me reconsider since they have good performance and the conversions appear extremely accurate (and the software is open-source). Well played.

Unfortunately, the charts hit the same issue as every other JS library in that they are nigh unusable on mobile devices for nontrivial visualizations. Which is beginning to get annoying.
