/ ROUND-TRIP DIAGRAM EDITOR
Edit industry-standard diagrams without losing the source.
Schematex keeps every canvas gesture as deterministic DSL. The editor exposes only the labels, axes, and native geometry that each diagram standard can change safely; all other structure remains explicit and reviewable in source.
