What does it mean that your graph grows by accretion?

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.

Try this: Open your knowledge graph (or start one today). Add exactly one node — a concept, observation, or principle from the last 24 hours. Then add at least two edges connecting it to nodes that already exist. Write one sentence explaining each connection. Do this every day for the next seven days. On day seven, count your total edges. You will have more edges than nodes, and several of those edges will surprise you — connections you did not anticipate when you added each individual node.
