A bubble series is another type of scatter series, like an XY series. Data points are
represented by bubbles spread across the chart area with respect to pairs of xy values
whose coordinates are calculated against a horizontal and a vertical scales. In addition to
the xy values, a third value(z) is aggregated to the bubble series in order to calculate
bubbles' diameters. The z value is commonly used to measure importance, in terms of the
diameter of each bubble displayed.
The number of values passed to the seriex_values parameter must always be a multiple
of 3. Every sequential set of 3 values is assigned to one data point, corresponding to the
x, y and z values.
The type of a bubble series is 'bubble'.
