## Emergence
**Emerges from:** [go](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-go.movement), [line](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-line.geometric), [extent](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-extent.spatial), [follows](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-follows.sequential)

**Through:** the movement follows the extent, tracing a line in spatial continuity

**Novel properties:**
- directional continuity
- spatial adjacency
- sequential alignment
