This is very cool. How do you output the data to use it?

I'm sure someone more versed in ObservableHQ has a smarter way but: I've added an `ObservableNode` that allows you to set a callback. In that callback I update the mutable variable `results`. It's a little hacky/finnicky but you get the idea. Right now this approach only works if you create `ObservableNode` dynamically (not via the LiteGraph context menu) where you can set your callback. Additionally when I change the input to the ObservableNode I sometimes see `results` stops updating.

Thank you this is very helpful!
