Generates an iOS bubble chart in code. See Documentation on how to use this type here: The iOS Bubble Chart Documentation.

iOS Bubble charts can be used to visualize multi-dimensional data on a 2D Chart, for example, using the Bubble size (Z property) and color can denote data of increasing importance or weight at an X-Y location.

The SCIFastBubbleRenderableSeries requires a SCIXyzDataSeries, which contains one Z-value per X-Y point. Bubble sizes can be scaled using the SCIBubbleSeriesStyle.zScaleFactor property.
