Version 2

• Coffeescript to Javascript
• Use d3 v4
• Change the way palettes works:
  • before: usePalette: <true|false>, paletteSize: 9, paletteName: 'Greens' and color attributes.
  • Now only color attribute that recognize palettes. PaletteSize is not anymore useful (color palettes are continuous)
• order of attributes:
  • before: track('name', conf, data)
  • now: track('name', data, conf)
• Input data can't be anymore an array of arrays. It has to be an array of objects with shapes defined in documentation
• There is no more 'rule'. The rules are handle with callback functions. For example in the configuration you can specify:

color: function(d) {
  return d.value > 5 ? 'blue' : 'red'
}
