Local planning inputs

Local processing without upload or storage.32KiB per field,1MiB complete result,one-second Worker deadline. Editing cancels work and clears old diagrams/exports. Edit text rows for keyboard positioning/reordering. No external map tiles or device location.

Diagram and data

Edit inputs and build. All previews are generated locally.

Processing model and limits

Weighted SVG ribbons on an acyclic directed graph. Node size=max(inflow,outflow); report imbalance instead of inventing conservation. Sum of all edges is traversed flow, not unique initial traffic. Cycles and nonpositive weights are 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
