Google Charts - Basic Bubble Chart


Advertisements

Following is an example of a basic bubble chart. 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.

//bubble chart
var chart = new google.visualization.BubbleChart(document.getElementById('container'));
