how to show two d3.js diagrams on the same page - html

Question

i read lots of threads and the Mike's blog but i haven't found how to solve my problem.
I'm using the donut chart of D3.js and everything works fine.
I use that code and change the value for each diagram:
var w = 650;
var h = 400;
var r = 150;
var ir = 75;
var textOffset = 24;
var tweenDuration = 1050;
//OBJECTS TO BE POPULATED WITH DATA LATER
var lines, valueLabels, nameLabels;
var pieData = [];
var oldPieData = [];
var filteredPieData = [];
//D3 helper function to populate pie slice parameters from array data
var donut = d3.layout.pie().value(function(d){
return d.itemValue;
});
//D3 helper function to create colors from an ordinal scale
var color = d3.scale.category20c();
//D3 helper function to draw arcs, populates parameter "d" in path object
var arc = d3.svg.arc()
.startAngle(function(d){ return d.startAngle; })
.endAngle(function(d){ return d.endAngle; })
.innerRadius(ir)
.outerRadius(r);

Here is the Jsfiddle of the diagram i'm using:
jsfiddle.net/brusasu/AqP73/
I created two html page, each for the diagrams with the value i need to show.
My question is how to edit the code in a way where i can use the two diagrams in the same html page.
Thanks in advance

Oki Doki. I'm no expert in these things, but looking at the css in your jsfiddle, it appears to be missing the styles that you might want for the divs "slidercontainer2", "pie-chart2 and "slider2".
Make sure that you have these properly duplicated and that will at least get you closer.
