Following is an example of a donut chart. 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 the pieHole configuration to set a pie chart as a donut chart.
// Set chart options
var options = {
pieHole: 0.4
};
