/**
 * Loading XML Data
 * by Daniel Shiffman.  
 * 
 * This example demonstrates how to use loadJSON()
 * to retrieve data from a JSON file and make objects 
 * from that data.
 *
 * Here is what the JSON looks like (partial):
 *
{
  "bubbles": {
    "bubble": [
      {
        "position": {
          "x": 160,
          "y": 103
        },
        "diameter": 43.19838,
        "label": "Happy"
      },
      {
        "position": {
          "x": 121,
          "y": 179
        },
        "diameter": 44.758068,
        "label": "Melancholy"
      }
    ]
  }
