Pie Chart With Custom Labels
This pie chart is configured with custom labels specified in
the data object. On desktop we use the labelOffset property
to offset the labels from the center. Also labelDirection can
be used to control the direction in which the labels are expanding.
Gauge Chart
This pie chart uses donut, startAngle and total to draw a gauge
chart.

CSS, with some minor suboptimal things, here's an example of
how to animate donut charts using Chartist.Svg.animate and
SMIL.
