Flowchart conventions

ISO 5807:1985 remains published and defines documentation symbols and conventions for data, program, and system flowcharts. Use it as a vocabulary and review aid. A renderer's shape names do not prove conformance.

Reference: ISO 5807:1985.

The standard is not bundled as executable validation in diagram.zip. Treat strict conformance checking as a possible future integration.
