Diagram Max in depth

Diagram Max

An original SVG diagram editor (not a Visio clone).

Drag stencils onto the canvas and connect node ports with orthogonal connectors that route around other shapes.
Five stencil sets with 25 shapes (flowchart, network, org, process and infrastructure) and nine templates.
Automatic hierarchical layout, top-down or left-to-right.
SVG and PNG export from the same geometry engine as the editor.

Ultra X27: adds nested groups and swimlanes, node positions you can pin through auto-layout, connector priorities, shapes linked to CSV data with a review step, and up to 32 conditional style rules.

Limits: Diagram Max uses its own file format and does not claim to import or export Visio files.

How it works

It is a separate desktop product on Culltron's shared, hardened platform, with its own full editor and local workspace.
A local, authenticated runtime serves the editor. Your files stay on your machine.
A signed licence lease unlocks the paid edition, and Ultra X27 features are enforced by the server, not just hidden.
Changes write new copies, usually with checksum receipts, so originals are not overwritten.
