Super cool! We need more graphs in the space. It reminds me of my last failed startup. https://github.com/woost/wust2

Everything was a node in the graph and could be connected and nested: folders, todos, notes, chat messages, even kanban columns.

We had big difficulties to sell, because nobody understood the concept. Or saw the advantages.

But yours is more visual and may be easier to grasp, because people today often already know Miro and Notion. I whish you best of luck and hope you succeed!
