I have been working on a project which displays the graphql schema as a diagram and I have been working closely with @schickling and @kuldar to get their feedback. I think it would be a very useful addition to graphql-playground. I am looking for feedback from the community to improve the library and hopefully include it in Playground!

We originally looked into using graphql-voyager, but the bundle size was ~2mb which is not at all viable to ship with playground. This tool is ~200kb and can be reduced further to ~80kb. There are very few options available in the javascript ecosystem to layout diagrams in the way voyager has, so a few design modifications had to be made. The main aspect is that we are using a "fog-of-war" strategy. You will see what I mean from the examples below.

Currently there are two options.

Option 1: Single links between types (even if multiple fields point to the same type)

Option 2: Links directly from fields to types

Some possible designs from @kuldar:

The diagramming library I am using (jointJS) is flexible, but some requests may be very difficult to implement or not possible, but please feel free to submit a PR!
