Data model for creating a radial bar chart with d3js - d3.js

Question

I'm trying to make radial bar chart using d3js, but I'm having some trouble with the data model. I have a fiddle here showing what I want to achieve. At the moment the size of the bars are randomly created, but I want to be able to provide my own data (values between 1 and 6) into the chart, but I'm having trouble understanding the data model/structure of d3js, so help would be appreciated!
$(function(){
var $container = $('.chart-container'),
τ = 2 * Math.PI,
width = $container.width(),
height = $container.height(),
outerRadius = Math.min(width,height)/2.5,
innerRadius = 10,
fontSize = (Math.min(width,height)/4);
var dataset = {
weeks: [1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1]
};
var color = d3.scale.ordinal() .range(['rgb(247,251,255)','rgb(222,235,247)','rgb(198,219,239)','rgb(158,202,225)','rgb(107,174,214)','rgb(66,146,198)','rgb(33,113,181)','rgb(8,81,156)','rgb(8,48,107)']);
var pie = d3.layout.pie()
.sort(null);
var arc = d3.svg.arc();
var svg = d3.select('.chart-container').append("svg")
.attr("width", '100%')
.attr("height", '100%')
.attr('viewBox','0 0 '+Math.min(width,height) +' '+Math.min(width,height) )
.attr('preserveAspectRatio','xMinYMin')
.append("g")
.attr("transform", "translate(" + Math.min(width,height) / 2 + "," + Math.min(width,height) / 2 + ")");
var gs = svg.selectAll("g").data(d3.values(dataset)).enter().append("g").attr("class", "arc");
var path = gs.selectAll("path")
.data(function(d) { return pie(d); })
.enter().append("path")
.attr("fill", function(d, i) { return color(i); })
.attr("d", function(d, i, j) { return arc.innerRadius(10).outerRadius(20*getRandomInt (1, 6))(d); });
});
function getRandomInt (min, max) {
return Math.floor(Math.random() * (max - min + 1)) + min;
}

Change your dataset variable and colours here, just pre-populate your required arrays and inject them into D3. i.e. d3.values(dataset)
var dataset = {
weeks: [5,10]
};
var color = d3.scale.ordinal().range(['#ccc','#c33']);
