useful use case

[gutama]

Hi John,
After seeing the exploration page, which is great :) , is it possible to display more information when hover above the node. e.g:

• in economic complexity hovering over a node will retrieve the product detail or its image.
• in cran-dependency will give the package description or just URL.
• in rtweet example we can embed or have floating screenshot from tweetrmd.

I understand that I have to capture the event click or hover, but how to put the retrieved information back.

thank you.
