I create mostly SAS/Graph output, and I set up almost all my jobs to run in batch mode, and have been using "ods html" almost exclusively for many years. I was glad to see the DMS SAS default recently change to ods html, as that makes my interactive DMS graph output very similar to my batch-job output.

One thing that I really like about html is that I can have html hover text (alt or title tags) on the pieces of the graph (bar segments, plot markers, map areas, etc) so I can hover my mouse over them and see the data values -- this helps a lot in verifying that the graph is representing the data the way I intended.
