A bubble chart is a type of chart that displays three dimensions of data. Each entity with its triplet ( v1, v2, v3 ) of associated data is plotted as a disk that expresses two of the vi values through the disk's xy location and the third through its size. The <Bubble3DChart> element tag is used to create a bubble chart in KoolChart, and the series element tag for the bubble chart is <Bubble3DSeries>.
