Pie charts using leaflet-semicircle

When using a single number, it is interpreted as a percentage:

L.pie([50.66, -0.0], 45).addTo(map);

You can also pass an array of {num: Number, label: String}-maps:

L.pie([50.68, 0.05], [
    {num: 45, label: 'Bob'},
    {num: 60, label: 'Tom'},
    {num: 45, label: 'Ada'}
]).addTo(map);
