[idea] tree view from top to bottom.

Would be interesting to have a tree view that shows dependencies from the chosen entry point as a tree from top to bottom, all arrows going downwards, and if a dependency imports th same module as already up higher in the tree then the graph just duplicates that dependency downward in the tree, and hovering on a dependency that is dupplicate (to see what imports it or what it imports) would highlight all instances of that node.

Start by reviewing the current force-directed graph report and how it represents CommonJS or AMD dependencies. Define the chosen-entry-point tree behavior, duplicate-node hover highlighting, and downward layout as done criteria before locating the relevant visualization code.
