Hello,

step1. Create Local database in neo4jtool  
 ![step2](https://us1.discourse-cdn.com/flex021/uploads/neo4jcommunity/original/2X/d/dd48221428b9028940345ae4efe8b4ea7ac1da10.png)

step2. write in javascript

```auto
const neo4j = require("neo4j-driver");
  const driver = neo4j.driver("bolt://localhost:7687", neo4j.auth.basic("TestGraph", "1234"),{encrypted: true});
  const session = driver.session();
  const start = new Date();
  let isDoneSession = session
    .run('Load csv with headers from "Datas/testtes2t.csv" as attackgraph create(a1:AttackGraph {attack_no: attackgraph.attack_no, attack_seq: attackgraph.attack_seq, from_id: attackgraph.from_id})', {limit: neo4j.int(5000)})
    .then(function (result) {
      const links = result.records.map(r => { return {source:r.get('source').toNumber(), target:r.get('target').toNumber()}});
      session.close();
      const ids = new Set();
      links.forEach(
        l => {ids.add(l.source);ids.add(l.target);}
      );
      var gData = { nodes: Array.from(ids).map(id => {return {id}}), links: links};
      const Graph = ForceGraph3D()(document.getElementById('MyIndexRenderers')).graphData(gData);
    })
    .catch(function (error) {
      console.log("Error!!!!!!!");
    });

```

The default user name is `neo4j` not `TestGraph`

you have to put the csv file into the import folder of your database and then use `file:///name.csv`

Best take the import training
