Build dinamic 2D Graph

[vincenzopalazzo]

Hi @anvaka,

I'm building a very big graph (more transaction Bitcoin) and I'm working with VivagraphJS but now I want to upgrade my project to ngraph, I'm studying the documentation and now I have some question:

• Is it possible to build a Graph dynamically? in the Vivagraph I have to Build the graph with this code.

  function buildGraph(){
  //Some config
  renderer.run();
  let fileBlkPromisse = self.dao.loadFileText(pathInput);
      await fileBlkPromisse.then(function(fileBlkData) {
                 // console.debug('File content: ', fileBlkData);
                  let lines = fileBlkData.split('\n');
                  let simpleRenderer = 0;
                  lines.forEach(line => {
                     if(simpleRenderer === 500000){ return; }
                      simpleRenderer++;
                      let token = line.split(stringToken);
                      let toNode = token[0];
                      //console.debug('To node with id: ', toNode);
                      let fromNode = token[token.length - 1];
                      //console.debug('From node with id: ', fromNode);
                      self.graph.beginUpdate();
  
                      self.graph.addNode(toNode);
                      self.graph.addNode(fromNode);
                      //console.debug('Information node is: ', token.slice(1, token.length - 1));
                      self.graph.addLink(toNode, fromNode, token.slice(1, token.length - 1));
  
                      self.graph.endUpdate();
                  });
                 // actualIndex++;
                  //pathInput = self.getNameFile(PATH_RES + 'tx/', '_tx.txt', actualIndex);
              }).catch(ex => console.error(ex));
  }

The method dao.loadFileText() use the fetch to load the file with all information.

How can run the renderer before I build the graph?

• For the moment to render the Big graph I'm using the ngraph.pixel + ngraph.forcelayout, you have a better solution for the velocity (also I'm thinking to use ngraph.native)?

I have some question but I create the question in the appropriate repository.

Thanks for your help

fix it with ngraph.pixi
