Just finished an episode of Learn with Jason showing how to use this to build a small Spotify app using the Netlify Graph tooling: https://www.twitch.tv/videos/1299016321?t=0h25m21s (the link starts at the first step of the new app and dives right into the experience)
Jason knew next to nothing about the current state of Netlify Graph (to keep the experience authentic), so it's pretty fun to see his reactions.
