The goal was to explore a way to draw big trees and still have the ability to zoom and scroll at interactive speeds. The prototype automatically collapses and expands nodes based on the available screen space. As the user zooms in, collapsed nodes will expand to show its children. The application also has an overview window to show the location of the current view in the larger tree.
