ng2d3 chart data formatting

[kyleledbetter]

It would be nice if we test & validate all the JSON formats for https://swimlane.github.io/ng2d3/
(seems like it will)

like

bar

[
  {
    "name": "Germany",
    "value": 46268
  },
  {
    "name": "USA",
    "value": 53041
  }
]

stacked vertical bar

[
  {
    "name": "Germany",
    "series": [
      {
        "name": "2010",
        "value": 46268
      },
      {
        "name": "2000",
        "value": 23685
      },
      {
        "name": "1990",
        "value": 22219
      }
    ]
  },
  {
    "name": "USA",
    "series": [
      {
        "name": "2010",
        "value": 48377
