[R] R and Interactive Visualizations

[Lorenzo Isella]

Dear All,
I use several R libraries (ggplot2, igraph etc...) for producing static  
visualizations.
However, I'd like to be able to go beyond this.
Things I may like to be able to achieve (relying on R as much as possible):

1) network visualizations such that when you click on a node, you see its  
properties and the network layout centers on that node
2) geographical plots (e.g. European countries colored according to their  
GDP and the possibility to see some other metadata when I click on one of  
them)
3) being able to select/deselect some dataset in a conventional plot (e.g.  
multiple stacked histograms)

and so on and so forth...

I did some online research and came across potentially many resources like

but I honestly have no idea about where to start from.
Making the interactive visualizations available on a website is a logical  
second step, but first things first.
I am sure that plenty of people on this list have a strong expertise about  
the interactive visualizations, so any suggestion is welcome.
Cheers

Lorenzo
