How do I specify the root node of a dependency graph? (both in the UI and in the json format)

Hi Greg!

I'll quote the notification on the recipe docs, you need to double-click.

The ROOT of the sentence needs to be connected to itself. You can achieve this in the relations interface by selecting the label and double-clicking or double-tapping a token.

To see the JSON requirements, it's usually easiest to annotate one example and to then inspect what it looks like from db-out. I'll demonstate this with a somewhat silly example. Suppose I have this examples.jsonl file:

{"text": "word1 root word2"}

Then I can run Prodigy via:

python -m prodigy dep.correct issue-6449 en_core_web_sm examples.jsonl

And it will render this graph:

CleanShot 2023-03-24 at 12.40.46

When I now save this I can see the output via db-out.

python -m prodigy db-out issue-6449 | jq

This is what it returns.

Ah, I missed that. Thanks!
