Spatial node based nav - very much like

I’m looking for some examples of this type of organic node based navigation, basically a sitemap come to life, if you will.

In the past I’ve ran into many sites that had examples of this but I did not book mark them and I can’t seem to find them anymore.

Any input or links would be helpful.

I also found this piece,, just as an example, but what I’m looking to get some examples on is if you click a node associated nodes would come out with lines drawn.

I’m in the process of just building this from scratch but I’d rather not re-invent the wheel.

Thanks Kirupa folk!
