dtc | Dataflow Tabular Chart

dtc is a Perl library. dtc has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

dtc takes a textual description of a dafatlow diagram and produces a graphical output of the diagram. It is very convenient to present complex transport and filtering systems in one synthetic view. The goal of the graphical representation is to convey information that is not usually available on a standard architecture representation: those representations usually show functional dataflows with no details on the transport mechanisms. DTC represents the protocol layers across the whole dataflow, allowing to show which device or service processes which part of the protocol layers. For example email.svg shows a simple, typical e-mail setup whereby the sender (on the right) sends e-mail to an SMTP server. The SMTP server saves e-mail in local files (maybe using Maildir). An IMAP server on the same system serves the local user. This diagram shows easily that a malformed e-mail message can reach right inside the protected domain.
