Basically, I'm trying to make Mathematica give me a tree with names inside the rectangles like so:
...while also having the properties of VertexLabels or Tooltip, which lets me place my mouse over the name in the rectangle to give me additional information. Using VertexLabels alone places the names outside the nodes, which I don't want. Nor do I want circles - they need to be rectangles. Tooltip alone doesn't seem to work for the nodes, only the edges. Any help will be much appreciated.
