From @puckpuck via https://cloud-native.slack.com/archives/C01NJ7V1KRC/p1775516334694159?thread_ts=1775508334.512039&cid=C01NJ7V1KRC:

@puckpuck - good question : not sure what happened April first. You're right, that graph and panel doesn't make sense. I'll open an issue.

Also, while in there, we might as well add the locale panel (see K8s Looker page).
