Following is an example of a basic timelines 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

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