After setting up Google Sheets as a data source, you can create a visualization from Google Sheets data in Superchart. Follow these basic steps:
Click "+Create visualization" to begin building from scratch.
After clicking create, you'll need to choose a data source.
If you have multiple data sources, choose Google Sheets as the data source.
After clicking Google Sheets and confirming, you'll choose a specific data set.
As a database in Superchart, select a Google Sheets spreadsheet. For a table, choose a sheet within that spreadsheet.
After you've selected a spreadsheet and sheet, you'll import your data.
Importing your data will take a one-time snapshot of the current information. Once connected to a specific Google Sheets spreadsheet, you can always refresh the data feeding a Superchart visualization.
From here, you'll be taken to configure a visualization from the Google Sheet spreadsheet and table you've chosen.
