GitHub's GraphQL schema Visualized

I was just confused because the title does not mention that it is a video and the title is not descriptive of the content. I thought the submission may be linking to the wrong thing or that there is a link to a pdf of the content on the page that I failed to see.

Personally I do not find video to be a useful medium for displaying static visual information. If I want to see how someone does a flip then sure but for looking at code or diagrams I prefer text or something similar. A possible use case for your project among developers might be demonstrating a bug. If someone has a bug associated with their choice of operating system, for example, it may be impossible for those who use other systems to reproduce and excessively tedious to describe in text format. It could also be useful for screen capture that is going to be turned into a gif for project demonstration.
