Hello Fellow Quakers,

I was wondering if anyone of you could help me to realise this page:

http://www.pro-ambiente.it/referenze.htm#

The idea is to hover over a dot i.e. a certain fixed location, which then displays the data in a dedicated frame. I would love to know how that works. Are there any tutorials?

Id love to just copy the source code but i cannot excess it. I am sort of a noob with web style sheets or however they are called. so take it easy on me. :)
