this should be feasible with D3. The way I understand it, is that you are trying to make node graph along a time series. So you basically just have one axis (date; usually plotted on the x-axis). The way I would plot it is to have a long horizontal scroll along the x-axis where a series of nodes are scattered in the single date dimension. Hovering (or clicking) over this node would expand a list of dependencies into the second dimension (distance from the original node might represent time; perhaps in two columns, past [depends on] and future [depended by]). Clicking on one of these dependency nodes would scroll you smoothly where this dependency nodes reside on the main axis. All of this is possible (and almost trivial) with D3. However you might need to be innovative in implementation as I don’t think there are easy examples for you to follow.
