> Can this visualize over data stored in Honeycomb like Grafana can?

IIUC, Grafana connects directly to Honeycomb via its API to visualize data without storing it. Instana, on the other hand, is a bit different. It needs telemetry data to be ingested into backend before it can be visualized in UI. With Honeycomb, this could be possible if the data can be exported from Honeycomb to Instana.
