I have a multi series donut chart created with the help of this question D3.js - Donut charts with multiple rings in d3.js, see fiddle below.

I'd like to be able to add hover effects, and also make each part clickable in the sense I'd like to assign a certin href to each slice of the chart. I have looked around quite a bit, but can't get my head around it - d3.js is quite complex for me I guess.

The code I have now: http://jsfiddle.net/mephisto73/o6shxw0d/

(function(){
var $container = $('.chart-container'),
        τ = 2 * Math.PI,
        width = $container.width(),
        height = $container.height(),
        outerRadius = Math.min(width,height)/2.5,
        innerRadius = (outerRadius/5)*4,
        fontSize = (Math.min(width,height)/4);

var dataset = {
  weeks: [1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1],
    months: [1,1,1,1,1,1,1,1,1],
    trimester: [1,1,1]
};


var color = d3.scale.ordinal()    .range(['rgba(141,211,199,0.8)','rgb(255,255,179)','rgb(190,186,218)','rgb(251,128,114)','rgb(128,177,211)','rgb(253,180,98)','rgb(179,222,105)','rgb(252,205,229)','rgb(217,217,217)','rgb(188,128,189)','rgb(204,235,197)','rgb(255,237,111)']);

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(innerRadius+(40*j)).outerRadius(innerRadius+(5*(j+5)))(d); });
});

I've added functionality for on mousemove, mouseout and click. Try to read and do the modification in click function. Hope you got it,If not ask me for more.
