[GitHub] [beam] damccorm opened a new issue, #19689: Create a CLI to convert a pipeline to graphviz dot format

damccorm opened a new issue, #19689:
URL: https://github.com/apache/beam/issues/19689

   As a Beam developer (especially one using python or go) I want a way to convert a pipeline to graphviz dot format so that I can easily visualize it.  
   
   The Beam source comes with a great utility in the form of [PortablePipelineDotRenderer.java](https://github.com/apache/beam/blob/2df702a1448fa6cbd22cd225bf16e9ffc4c82595/runners/core-construction-java/src/main/java/org/apache/beam/runners/core/construction/renderer/PortablePipelineDotRenderer.java#L29). It seems like a great util to wrap with a CLI, so that it can be easily accessed from other languages and just for general ease-of-use for java developers.
   
   The tool would take an input pipeline message as either a path to a file or via stdin, and would output a dot string to stdout or to a file.
   
   I'm happy to make a PR for this.
