This is a demo of a chart being created by using the Google Sheets connector that's bundled with RGraph. You can see the Google Sheet that RGraph is fetching data from here and the documentation for the Google Sheets Connector here.
It's using the data that's on the Bar worksheet (there are multiple buttons at the bottom of the screen that allows you access to the other worksheets). The labels are coming from the spreadsheet too.
The stroke color is set to white and the linewidth is 2. There's no other configuration so the Pie chart looks quite standard, though there is a responsive configuration so that on smaller screens the labels disappear and tooltips are used instead.

<div style="width: 650px; height: 300px" id="chart-container"></div>This is the code that generates the chart - it should be placed AFTER the
