After signing up for Superchart, you'll land on the Data Sources page. Follow these steps to connect Airtable data:
Click "+ Airtable integration" to create Airtable charts in Superchart. You'll be asked to connect your Airtable account.
You'll be presented with a familiar Airtable login prompt.
Sign in to Airtable as a first step. If you're already logged in, you may skip past this step.
Once you're into an Airtable account, you'll be presented with an access request for Superchart.
You determine which base(s) to which Superchart has access. Add at least one. You can always go back into Airtable and modify the access fairly easily. It's best to pull in only what is necessary. Click "Grant access" when you're all finished selecting Airtable bases.
Superchart will grab the basic info on tables and fields from Airtable. After loading, you will see a list of Airtable databases, tables, and views upon which you can create Superchart visualizations.
Now that Superchart has access to view your Airtable data, get started building a visualization.
