Grafana really looks interesting, and it is interesting that you can add all the different backends to it, for an example I didn't know you can use Elasticsearch as a timeseries backend.
Is it correct that Grafana works best with Graphite? At least that seems to be my impression, and it is a bit sad, since I think Graphite is cool, but it really has a lot of moving parts.
I wouldn't let that stop you from evaluating it. At my last few jobs I've used Grafana with Elasticsearch and Prometheus without a problem. I've never actually used it with Graphite. The only downside I've seen is that the queries are unique to the data source, so when looking at many of the examples online you have to figure out the equivalent for your's. There might be a performance difference, but I wouldn't know it since I haven't used Graphite.
Today after fighting with Kibana all morning, I decided to tweak our scripts to build Grafana dashboards against our existing ElasticSearch data store. Very fast to get up and running and the the features and speed are amazing.
