title: Which D3 visualization/layout is suitable for Data Lineage?
body: <p>As a newbie loving D3, I am trying to visualize data movement from source to destination that goes through multiple systems.  But I am having hard time identifying suitable layout.  Tried using Chord and Tree but don't know how to represent intermediate systems visually. Are there any recommendations/rule of thump on which layout/diagram is more appropriate for a given purpose (e.g.data lineage)?</p>
