Hi,

Sorry if the answer is really simple. But I'm looking for a expandable tree visualisation (like file organisation with plus or minus sign on the left to expand the tree). As the file is quite big. ~12000 rows. and with possible 5 layers (so there are index numbers like 1.1.1.1.1 to make then into different classes). I programmed in tk and ggobi, both are very slow as it loads the data all at once and cost about 5 seconds just to load 2000 files. Is there an automatic way of doing this?

Many thanks.
