Tested and this looks pretty good to me, LGTM

Side note: To be able to use it for Visualize / Lens, the unified renderer needs to be able to pick up formatting from the table, seems like this is not the case yet:

kibana | kibana_context savedSearchId=null timeRange={timerange from="now-7d" to="now"} | esaggs index={indexPatternLoad id="90943e30-9a47-11e8-b64d-95841ca0b247"} aggs={aggTerms id="0" enabled=true schema="segment" field="extension.keyword" orderBy="1" order="desc" size=5 otherBucket=true otherBucketLabel="Other" missingBucket=false missingBucketLabel="(missing value)"} aggs={aggAvg id="1" enabled=true schema="metric" field="bytes"} metricsAtAllLevels=false partialRows=false |
metricVis metric={visdimension accessor="col-1-1"} bucket={visdimension accessor="col-0-0"} showLabels=true labelPosition="top" labelFont={font size=24 align="left"}
