Yesterday, we shared with you details about the upcoming release of jQWidgets which will include a new Pie Chart. You can read more about it
here. However, the Pie Chart is not the only new Chart type planned for the release. You should also expect new Scatter and Bubble Chart types.
A brief description about the Scatter and Bubble Charts:
The Scatter Chart uses Cartesian coordinates to display values for two variables for a set of data. The data is displayed as a collection of points, each having the value of one variable determining the position on the horizontal axis and the value of the other variable determining the position on the vertical axis.

The bubble chart is a variation of the scatter chart. The bubble chart is a type of chart where each plotted entity is defined in terms of three distinct numeric parameters. Bubble charts can facilitate the understanding of the social, economical, medical, and other data.
