I just discovered an awesome new tool to visualize and interact with the application schema: GraphQL Voyager. It enables to have a bird eye's view of the schema, and zoom in into the different types, their properties, and the relationships with other types.
Since my GraphQL server is integrated to WordPress, it is very easy to visualize all the relationships from the WordPress database.
(I'm still completing the different types, properties and relationships in my schema, so this visualization still does not mirror the whole WordPress data model... this will hopefully be finished in the upcoming weeks.)
This is how the interactive GraphQL looks like (even though a bit compressed here!):
This is such a powerful and beautiful visualization of the data graph. Kudos to the contributors from this great project!
