You can install package from Github.
# install.packages("remotes")
remotes::install_github("devOpifex/g2r")
library(g2r)
g2(cars, asp(speed, dist, color = dist)) %>%
fig_point(asp(size = dist)) %>%
gauge_color_viridis()
g2r currently does not work well with large datasets (performance drop), and some features are still under development, namely rmarkdown actions, shiny proxies, and maps. Theming is currently rather unwieldy.
