how to integrate perfkit benchmarker results into perfkit explorer

[ayamResearch]

./pkb.py --project=testgcp --benchmarks=iperf --machine_type=f1-micro --bigquery_table=testSamples_mart.results --bq_project=testgcp

using above mentioned command run the perfkit benchmaer and creates bigquery table on google bigquery. I have uploaded the perfkit benchmarker results using command on
bq load --project_id=testgcp --source_format=NEWLINE_DELIMITED_JSON ./testSamples_mart.results

testgcp provides a link to the dashboard-admin, however, I am not sure how to use this dashboard to visualize the results of iperf.
Appreciate your help
