Diagram and data
Edit inputs and build. All previews are generated locally.
Processing model and limits
Exhaustive ≤4096 typed cases and≤100 rules. Omitted fields or * are wildcards; explicit arrays are OR. Report every gap/overlap/unmatched rule, not first-match semantics. Unknown fields/domain values rejected. Local data only. Each field ≤32 KiB; ≤200 records, ≤80 graph nodes/300 edges, JSON depth30/nodes10000, ≤2000 coordinates. Complete result ≤1 MiB; diagram ≤8 million pixels and16384px per side. Edit text to move/reorder items; build again. SVG is a readable model, not an externally rendered image.
How to use this tool
Edit the labeled text fields, build, inspect the diagram and data, then copy or download JSON/SVG. Text editing provides the keyboard alternative to dragging.
