    <para>The <emphasis role="bold">Bubble </emphasis>visualization method
    creates a bubble chart from two-dimensional data. A bubble chart is a
    variation of a scatter chart where data points are replaced with bubbles
    and the size of the bubble is represented by a dimension of the
    data.</para>
