ngraph.forcelayout.nd v1.0.0

ngraph.forcelayoutNd

Experimental N-dimensional force based graph layout. It supports graph layout in multidimensional spaces (2+), using higher dimensional orthant trees (similar to quadtrees, but generalized to multidimensional spaces). While this layout is very generic and supports higher dimensions, it is still much slower than specialized 2d and 3d layouts.

usage

// let's say you have a graph instance:
var graph = require('ngraph.graph')();
graph.addLink(1, 2);

var createLayout = require('ngraph.forcelayout.nd');
// to create 2d layout:
var layout2d = createLayout(graph, {
  dimension: 2
});

// to create 4d layout:
var layout4d = createLayout(graph, {
  dimension: 4
});

// Once you have layout, call it iteratively:
layout2d.step();

// You can then get positions of each node:
graph.forEachNode(printPosition);

function printPosition(node) {
  var pos = layout2d.getNodePosition(node.id);
  // pos[0], pos[1] - will represent x, y coordinates of a node.
}

install

With npm do:

npm install ngraph.forcelayout.nd
