title: Using Graphviz / yed to produce a timeline + graph
body: <p>I had an idea of representing something like a family tree where nodes are connected by directed graphs but to add an additional dimension of time on the y-axis. So imagine the top of the page representing 1900 and all the way down to the bottom being 2020. </p>

  <p>Is there a way to do something like this in Graphviz or yed? Basically auto layout a specified digraph but the position of nodes on the y axis is linked to time?</p>
