Andrew Purtell resolved HBASE-1805.

    Resolution: Later

> Cluster status and region topology visualization
> ------------------------------------------------
>                 Key: HBASE-1805
>                 URL: https://issues.apache.org/jira/browse/HBASE-1805
>             Project: HBase
>          Issue Type: New Feature
>            Reporter: Andrew Purtell
>            Priority: Minor
> There are several FOSS options for in-brower interactive data visualization. For example:
>     Protovis: http://vis.stanford.edu/protovis/
>     Flare: http://flare.prefuse.org/
>     Javascript InfoVis Toolkit: http://thejit.org/
> The master GUI is of limited utility for dealing with really large tables or large clusters.
It occurs to me looking over some of the examples/demos of the above that both HBase cluster
status and region topology could be profitably rendered using such toolkits. 
> For example, go to the Flare demo page: http://flare.prefuse.org/demo . Click on Layouts.
Iterate over the sub options. Could be rendering region structure ... navigate and click through
for metadata. From there, hyperlink to actions or back to navigation. A pure Javascript example
of something like this can be found here: http://thejit.org/Jit/Examples/Spacetree/example1.html
> Go back to the Flare demo page. Click on Treemap.  Another visualization suitable for
tables. A pure Javascript analogue can be found here: http://thejit.org/Jit/Examples/Treemap/example2.html
