Diagrams are the key similarity though. Sometimes I 'see' spider diagrams, ordered and prioritised ideas (hierarchical diagrams), for and against tree diagrams, or ideas as though plotted onto a ball of string (more depth closer to the middle). Then again my educational background was project management, STEM and Psychology with most of my ideas that 'plot' like daisy chains, scatter diagrams, waterfalls (a, down a level, b, down, c), head-body-limbs, categories, star shapes, rings, keyword pair associations or Venn diagrams as if interconnected memory recall modules (dyslexia epitomised also ;-).The "Spider Web" visualization is Ne. Ni looks more like a flow chart. Now of course flow charts and spider webs do look similar but one focuses on the expansion and interconnections of the present while the other focuses on projections.
Your experience seems more Ne to me as well since you were aware of the connections and relevance of things in the moment due to Subjective Sensation (Si) and Objective Intuition (Ne).
