How to create in grasshopper similar complex dynamic data driven visualizations like this example in flash?

surely within the framework of grasshopper.

huge amount of data needed at first ;]

The creation of the graphs should be possible (you should have a list of connections, each node will be placed around a circle, and you create a bi-arc between the two (possibly with the tangents in the centre of the circle). You can even tweak it a bit if you want to add the nodes.

As mateusz suggests: the dataset will be a bit tricky to import: and also is the interactivity quite a problem. But I can imagine that you can filter out certain lists with a cull list item or something?

i think you should start with making a database in open office calc, you can easily import all the data with gHowl components.if you would like to make smth like map your moves, you'll need : city name, azimuth (from base point - in this case its new york), distance, population etc. see attached files for example..

Attached a very simple curve type solution. You get intersecting curves this way, you may need to add some sort of bezier scaling factor to avoid that.
