I'm still having some trouble figuring it out. It doesn't help that I don't have much JavaScript experience. I looked at the controller post. In order to 'bufferize nodes', should I implement the request function to only call onComplete() when the level is less than N? Should we continue this conversation on the Google Group? Thanks for your help. Thanks for the advice, Nicolas. I’m still having some trouble figuring it out. It doesn’t help that I don’t have much JavaScript experience. I looked at the controller post.

However, you can set a controller to your treemap that allows it to bufferize nodes. That means that even when having a larger tree, you can force the TM to display only N levels below the actual root. As you traverse the tree, it will make requests for new nodes to be displayed while deleting unnecesary nodes and thus keeping a smaller number of nodes in memory. If you want to know more you can check the on controllers post and the example source for the Spacetree (packaged in the library). Hope this helps Hi Benjamin,

I am looking at generating a Treemap with about 5000 nodes. About 70 are top level. The JSON string ends up being huge, about 800k, without any compression. Will the treemap be able to handle this size tree? Thanks, Ben I was wondering if there is a practical limit to the number of elements in the treemap.
