|Bubble Charts are a convenient way for graphical representation of multi-dimensional data. The data points are displayed as circles (or other shapes) with variable parameters (size, position etc.) that depend on the input data. For example a 2D Bubble Chart can represent a data set with up to 4 dimensions: X position, Y position, Size and Color.
The example shows a product comparison by three parameters - accuracy, expected life and number of sales. The Y and X axes use numeric scales. The title uses soft shadows and the legend is docked to the bottom of the chart area.
