Aggregate view of relationships + timings

[pauldraper]

There is currently a Dependency view, which is interesting, but Zipkin has a lot more data for which it could provide visibility.

I'm thinking of an aggregated view of parent-child relationships (including multiplicity) and timings.

There are a few ways you could arrange the data. This is my stab for a hypothetical system with X, Y, and Z:

X --2.5--> Y (8ms) --2.0--> Z (2ms)
 \
  \--0.5--> Z (6ms)

Each X has 2.5 Y children (8ms each) and 0.5 Z children (6ms each), and each Y child of X has 2.0 Z children (2ms each).

This doesn't show sequences (not sure how to "average" those), just parent-child chains and timings.
