Ref: https://github.com/openshift/console/blob/master/frontend/packages/console-shared/src/components/dashboard/utilization-card/UtilizationItem.tsx#L84

the check: `data.every((datum) => datum.length)` return true for `data.length === 0` but we actually want also to cover `length === 0` as no data (e.g. false)
