So once you correct the quote issue I pointed out in the comments above, either escape or switch the outer quote to be single quotes, this javascript will parse your input and get it ready for the donut graph
var dataArr = [];
var obj = $("#shipments-by-service-type-simple").data('shipments');
for ( var prop in obj) {
dataArr.push({"label": prop, "value": obj[prop]});
}
Morris.Donut({
element: 'donut-example',
data: dataArr
});
Here is the jsbin. It appears that raphael doesn't like the decimal values and is throwing errors. Might want to round your values
