#Radial Bar Chart

A D3 reusable radial bar chart (examples).

###Simple example

var data = [{'data': {'Winter': 5, 'Spring': 8, 'Summer': 12, 'Autumn': 9}}];
var chart = radialBarChart()
  .barHeight(250)
  .domain([0,15])
  .barColors(['steelblue']);

d3.select('#chart')
  .datum(data)
  .call(chart);

###Implementation

The implementation follows the reusable charts convention proposed by Mike Bostock.

##Configuration

The chart can be configured in a number of ways (all optional)

• margin: An object specifying the margins e.g. {top: 20, right: 20, bottom: 20, left: 20}
• domain: The domain of the data e.g. [0, 10]
• barHeight: The maximum bar height: this determines the overall size of the chart
• barColors: An array specifying the bar colours. Repeats if shorter than the number of bars.
• colorLabels: Colour the labels the same colour as the bar (boolean)
• tickValues: An array specifying axis tick values e.g. [20, 40, 60, 80, 100]
• tickCircleValues: An array specifying background circular grid line values e.g. [0, 10, 20, 30, 40]
• capitalizeLabels: Capitalises the data labels
• reverseLayerOrder: Reverse the order in which the layers are rendered
