It would be useful for me to visualize members of a project that don't necessarily have any hierarchical structure.
The org chart requires a supervisor id and even if you plug in a garbage value it doesn't give you a ton of freedom on drag and drop.
I got around this by using a dataset and some custom cards which works well enough for my purpose! But the org chart seems more powerful. The org chart automatically creates a card for every employee. My workaround requires duplicating a card as a template dragging/dropping rows etc.
It's still damn useful but I'd love to see if this is possible in some other fashion.
