What is incremental graph building?

Incremental graph building is a concept in personal epistemology: Add new nodes and edges daily and the graph becomes increasingly powerful over time.

Example: A software architect adds one node per day to her personal knowledge graph — a design pattern she encountered, a failure mode she observed, a connection between two previously separate domains. After six months, the graph has 180 nodes. But because each node connects to an average of 3.2 existing nodes, the graph contains over 570 edges. She didn't plan for the moment when searching 'performance' would surface a connection between database indexing, team communication overhead, and cognitive load theory. The graph surfaced it because accretion had built density she never explicitly designed.

This concept is part of Phase 18 (Knowledge Graphs) in the How to Think curriculum, which builds the epistemic infrastructure for knowledge graphs.
