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 the Google Charts Configuration Syntax chapter. So, let’s see the complete example.
Configurations
We’ve used BubbleChart class to show the bubble-based charts.
//area chart
var chart = new google.visualization.BubbleChart(document.getElementById('container'));
