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.
