Pie charts

Best for “share of a whole” — a handful of categories sized by their proportion of a total.

The first keyword is pie. An optional showData — before or after title — appends each slice’s raw value to its legend entry. The title may sit on the pie line (as above) or on its own line.

Each remaining line is a slice: "Label" : value (the quotes are optional). Values are numbers; a slice with a non-numeric or negative value is skipped, so a chart never fails to render. Slice angles and colors are computed automatically.
