> Based on SAMZA-1178, we are able to generate the JSON representation of
> StreamGraph and ExecutionPlan. We need to provide a visualizer to render the
> json as DAG and let users to view it.
> First look: https://xinyuiscool.github.io/visualizer/plan.html. This is based
> on the example graph JSON generated in TestJobGraphJsonGenerator.
> For the api-test job:
> 
> For the join-test job:
> 
> How to visualize the plan (locally):
> Once a Samza application (using fluent API) is deployed, an execution plan
> will be generated by the ExecutionPlanner. The plan JSON will be written to a
> file (plan.json) under the bin directory, which also contains the plan.html
> and javscripts (js folder). So the bin dir has the following for
> visualization:
> ./bin
> - plan.json
> - plan.html
> - /js
> - d3.js
> - dagre.js
> - planToDagre.js
> Then deployed locally, the user can directly view the plan by enter the
> following in a browser:
> **file:///my/samza/app/dir/bin/plan.html**
> To visualize the plan remotely, the user can either scp the files into local
> box and view the plan there, or bring up a simple http server to serve the
> page.
> In the future when we have the Samza dashboard, we can add the plan
> visualization there to avoid the above manual steps.
