Help approaching a 3D UI

I have a question about which area to research in order to achieve my MVP concept, I come from the film VFX world and have a technical mindset but dont know code. I chose UE for this because I have used it in a film/virtual production context before and I know I can use blueprints for an MVP.

I want to represent a large family tree dataset as a 3D node-tree, like a bunch of connected bubbles using depth to convey time.

While its technically a Ul should I really be creating this with meshes and thinking about the nodes as objects as they are navigable in 3D space? Should I be using the procedural mesh generation system?

What is the best way to load and edit this kind of data (GEDCOM family tree data) and use it to generate the nodes?

Thank you in advance, apologies for any bungled terminology.
