Bubble Charts are used to visualize data in 3 dimensions. It is very similar to Scatter Chart except that size of bubble represents another parameter. Out of the three parameters required (x, y, z), x & y determine the bubble's position on X & Y Axis whereas z determines its size. Given example shows simple ASP.NET MVC Bubble Chart along with source code that you can try running locally.
