Questions / Comments:

If only one 100% item there will be no pizza at all :)

Add below before line 144 and we get a round cirlce, probably som operator thats wrong that now allow single data item with value 100, but 99.9999 seems fine.

if (data.length === 1){
var singlePie = data;
data = [];
data.push({
value: 99.9999,
color: singlePie[0].color,
segment: singlePie[0].segment
});
}
