    ngraph.offline.layout

    Performs offline 3D layout of large graphs and saves results to the disk. This is somewhat experimental.

    The results are saved into data folder by default.

    usage

    // Assume you have a huge graph (instance of ngraph.graph):
    var graph = require('ngraph.generators').grid(10000, 10000);
    var createLayout = require('ngraph.offline.layout');
    var layout = createLayout(graph);
    layout.run();

    This will run the 3d force-based layout for 500 iterations. Each 5th iteration is saved into ./data/{ITERATION_NUMBER}.bin file.

    The layout can be configured with options argument:

    // run only 100 iterations
    var layout = createLayout(graph, {
      iterations: 100, // Run `100` iterations only
      saveEach: 10, // Save each `10th` iteration
      outDir: './myFolder', // Save results into `./myFolder`
      layout: require('ngraph.forcelayout3d') // use custom layouter
    });

    After all iterations are completed, the final positions.bin file will be saved into outDir. This file consists of Int32's written in Little Endian format. Each node of the graph is given three integers in the output file. The order of positions matches the order of graph traversal for graph.forEachNode() method.

    If the outDir contains data from previous run the layouter will attempt to resume based on the last saved iteration. If you don't want this, you can tell it to overwrite existing files:

    var overwrite = true;
    layout.run(overwrite);
