Series Components proposal

This is currently just a proposal.

c3-series

<c3-chart>
  <c3-series
    label=''
    data=‘[] ([{x:X,y:Y}], [{foo:bar, bar:baz}])’ // load data as a series array, or a more complex object (default keys would be x and y, but you could specify custom keys with `keys`, below:
    keys=‘[] ([‘foo’, ‘bar’])'
    type=‘line (spline, area, area-spline, step, area-step)’ // series type, would override type specified in c3-chart
    class='' // custom class name
    color=‘' // line color
  />
</c3-chart>

Params to consider:

• data-url='’ and data-url-mime-type: ‘': load data via a URL - http://c3js.org/reference.html#data-url
• label-format='': custom label format - http://c3js.org/reference.html#data-labels-format
• regions='': http://c3js.org/reference.html#data-regions
• group='': for bar stacking - http://c3js.org/reference.html#data-groups
• bar-width='': for bar charts
• bar-ratio='': for bar charts
• hide: hide this series
