Google Charts - Basic Donut Chart



Following is an example of a donut chart. 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 pieHole configuration to set a pie chart as donut chart.

// Set chart options
var options = { 
   pieHole: 0.4
};
