[jira] [Created] (SPARK-7628) DAG visualization: position graphs with semantic awareness

Andrew Or created SPARK-7628:

             Summary: DAG visualization: position graphs with semantic awareness
                 Key: SPARK-7628
                 URL: https://issues.apache.org/jira/browse/SPARK-7628
             Project: Spark
          Issue Type: Bug
    Affects Versions: 1.4.0
            Reporter: Andrew Or
            Assignee: Andrew Or


Many streaming operations aggregate over many batches. The current layout puts the aggregation stage at the end, resulting in many overlapping edges that together form a piece of beautiful artwork but nevertheless clutter the intended visualization.

One thing we could do is to put any stage that has N incoming edges on the next line rather than piling it up vertically on the right.
