JavaScript Charts Bubble Chart

Overview

JavaScript Bubble Chart is like a scatter chart, but allows you to visualize data in 3 dimensions. The size of the bubble is determined based on the third parameter.

Customizing each point in bubble

Appearance of each data point in a bubble chart can be customized using point render event to differentiate each point based on the size.

Data label

The JavaScript Bubble Graph data labels display information about data points. Add a template to display data labels with HTML elements such as images, DIV, and spans for more informative data labels. You can rotate a data label by its given angle.
