Google Charts - Bubble Chart with labels


Advertisements

Following is an example of a bubble chart with data labels. A bubble chart is used to visualize a data set having two to four dimensions. The first two dimensions are visualized as coordinates, the third as color and the fourth as size. We've already seen the configuration used to draw this chart in Google Charts Configuration Syntax chapter. So, let's see the complete example.

Configurations

We've used BubbleChart class to show bubble based chart.
