In Infer and Visualize Database Schema we've visualized array type simply as `[]`.

As a potential improvement, we could visualise the type of the items. But this is not straight-forward, especially when it gets to nesting and mixed fields. We'll need to make a decision, perhaps look around what other tools are doing.

Example formats:

• int[], int[][], (int, string)[]
• [int] , [[int]], [int, string]
• array with items: int child..
