UnitGraph example, loading graph and finding closest nodes

graph_unitgraph_closest_example.js

let ug = require('ug');

let graph = new ug.Graph();

// load graph from flatfile into RAM
graph.load('/path_to_saved_graph.ugd', function() {

  // get the closest 100 'listings' nodes, at a minimum depth (distance) of 3
  let results = graph.closest(node, {
    compare: function(node) { return node.entity === 'listing'; },
    minDepth: 3,
    count: 100
  });
  
  // results is now an array of Paths, which are each traces from your starting node to your result node...
  let resultNodes = result.map(function(path) {
    return path.end();
  }));
  
  doSomething(resultNodes); // render, whatever you'd like
  
});

Shouldn't line #16 read:
let resultNodes = results.map(function(path) {
?

// load graph from flatfile into RAM
graph.load('/path_to_saved_graph.ugd', function()

What is a ugd ?
