Hi, Thank you for your answers, I can not generate it with the java API since, I want a big graph (more than 1 million nodes and rel.), So I have to search about Batch-Inserter-API and understand it or do something like what Marko said. I thought there is a generated graph for stress tests! Any way, your answers really helped. Thank you a lot.
