No graph visualization for BTC dataset


I am using Neo4j Browser version: 3.2.17, Neo4j Server version: [3.4.7].
Platform: Windows Neo4j Application.

I am trying to import a .nt file into neo4j to view the graph visualization using the below code <CALL semantics.importRDF("file:///Users/arunk/Desktop/RA/btc150M.nt","N-Triples", {shortenUrls:false, commitSize:500})> and it is getting imported successfully and i can see the number of nodes, properties etc but not the graph visualization.

The dataset has 300k nodes and it belongs to BTC(Billion Triple Challenge). Could you please help me out.

How do you try to visualize it?
Can you share a screenshot?
