Rexster (Titan 0.5.1) is not showing default graph

Question

I've installed titan (0.5.1) from link titan-0.5.1 I ran command sudo bin/titan.sh start , Then I started bin/rexster-console.sh

Then, I went to http://localhost:8182/graphs/ it is not showing default graph. graph list is coming as empty.

{
"version": "2.5.0",
"name": "Rexster: A Graph Server",
"graphs": [],
"queryTime": 3.082986,
"upTime": "0[d]:00[h]:00[m]:57[s]"
}

Can someone help me to create graph using Rexster.
