h3. Bubble Chart
{anchor:bubblechart}
A bubble chart draws bubbles for each point in a series. The chart expects three values per bubble: the domain (commonly the X-axis) value, the range (commonly the y-axis) value, and a third value (the Z value) that determines the size of the bubble to draw around the point.
The size of the bubble is derived from an algorithm that takes the Z value, divides it by the maximum Z value in the dataset, then multiplies that number by the *max-bubble-size* property value. See the section on required properties below for more information on the *max-bubble-size* property.

This chart expects its data as an [XYZ dataset|The XYZ Dataset].
