I think the DPG docs is enough that it let you know those 3 data: link_id, link_id1, link_id2.
Lot of thing docs will not do research for you.

Either link_callback or delink_callback can further get info about the link or link's input/output (which attribute belong to which node).
Using get_item_parent, get_item_children, get_item_type, get_item_alias, get_item_configuration, get_item_info, get_item_rect*, ... like there are 27 get_item in the api docs.

Then you control the data yourself (graph theory, serialize/deserialize file, spawn/kill thread/process, connect/modify database,...).
I think these points will help in controlling the data:

• Item which is children of node_attribute, or any item inside/outside of the node editor will:
  • use callback, drag_callback, drop_callback.
  • use item handlers.
  • use frame callback.
  • ...
• mouse click, mouse release, mouse drag, mouse down, mouse move, mouse wheel, plus key modifier like: Ctrl, Shift, Alt.
• even draw a grouping rectangle (viewport_drawlist - front=True) or dashed line (draw_line or plot's line_series).

I hope you will investigate the site-packages\dearpygui\dearpygui.py file, view this file in vscode you can search these:

• node - 235 keywords.
• NodeCol - 32 keywords.
• NodesCol - 26 keywords.
• NodeStyle - 26 keywords.
