I have successfully created a graph with 1 million node and 1 million relationships. I am using 8 GB memory, 16 GB storage. 2 cpu auradb GCP hosted instance. I can query and sample the graph in neo4j query browser. However, when I click on the explore browser it keeps showing a solar blinking animation, the usual animation, to show explore is work to bring a sample graph. It never stops, and has been running for about an hour.
