I'm new to Gatsby, and I'm having trouble understanding how the graphiQL interface is populated with a default query.
I'm comparing two Gatsby starters. One is called photo book and the other is called gatsby-creative. I've downloaded and successfully executed both in develop mode. Both starters do in fact have graphQL queries used in the respective projects. However, when I visit the graphiQL interface for both starters I notice the first starter has no default graphql content (left-most column) whereas the second starter does have a default query called MyQuery.
What part of a Gatsby project controls whether there is a default query shown in the graphiQL interface? I can't figure it out and I've seen no documentation to explain this behavior.
Also, that second starter does have several graphQL queries, but none of them are named MyQuery (search for "myquery" turns up nothing). So it is particularly mysterious to me how the graphiQL interface obtains (or not) its default query.
Again, in what part of a Gatsby project should I look to discover which graphql statement is or is not part of pre-populating the graphiQL interface?
