Talk about a coincidence, I've been looking into Graphite dashboard options over the past few days too and came across most of these packages. So far the builtin Graphite dashboard seems at least as good or better than most alternatives. You can group multiple series in the same plot by simple drag and drop, tweak dozens of different parameters and save configurations, all from a web interface; no coding, committing and pushing to repos required. I'd love to hear impressions from anyone with experience in one or more of the above.
I agree the default Graphite dashboards are very flexible, but I need something that looks good for an overview page I'm hacking up for a monitoring dashboard in Openstack.
I've been doing the same thing, and we've been using gdash for awhile now, and we love it. Easy to use straight up graphite graphs with it on a nice full screen page.
Here are a few JavaScript graphing libraries as well: http://square.github.com/cubism/ and http://square.github.com/crossfilter/.
