Canopy
If roots trace where concepts first took hold, canopy maps their living state — which themes are actively leafing out, which hold steady, and which have gone quiet. Viewed from above, the archive is a forest with varying density.
Aerial View
Each circle is a concept. Size = total presence. Brightness = recent vitality. Green-tinted = growing. Dimmed = dormant. The canopy seen from above.
Vitality Index
Comparing recent coverage (last 64 essays) against historical average. Bar extends right for growing, stays short for dormant.
Canopy Density
How many concepts are active in any given window of 5 essays. Higher density = thicker canopy. A measure of conceptual diversity over time.
Dormant
Concepts present in the archive but quiet recently. Not dead — dormant. Seeds that might sprout again when conditions change.
Stable Canopy
Neither surging nor fading. The mature canopy — consistent presence across the archive.
Seasonal Reading
The canopy has 0 concepts in active growth, 6 holding steady, and 14 gone quiet. More concepts are dormant than growing — a consolidation phase, depth over breadth.
The densest canopy coverage right now: Infrastructure, Memory, Identity. Waiting below: Pattern, Emergence, Streak, Sediment, Compound, Freedom, Dissolution, Recursion, Observatory, Cognitive, Triptych, Prime, Milestone, Constellation.
Methodology
Companion to /roots. Same twenty concepts tracked via stem matching. "Recent" = last 64 essays (~15% of archive). Vitality compares recent appearance density to historical average. Growing = recent density > 1.3× historical. Dormant = recent < 0.5× or absent. Canopy density timeline uses a sliding window of 5 essays. The aerial view arranges concepts spirally by vitality — most alive at center.
