Hello!
I have this really simple plot example below using ggiraph to make it interactive. I have seen that this. You will see that in the example below we run gg_crime which is the ggplot version and finally the interactive one via girafe.
My question is - how to best control ggiraph output?. With ggplot I can decide on the graphics device etc to save the plot and make a really large DPI etc. I am able to control the width and height of the animated plot but I want to know how best I can control all other things such a DPI etc as I want to optimise this plot (my real problem has a really complex dendrogram with over 90 entries) and I want to optimise it for viewing at 1920 x 1080.
Any recommendations on how best to achieve this? Even if I could get the animated plot to inherent the original ggplot elements I would be glad cause as you can see the outputs are not the same with defaults.

library(ggiraph)
