What it is
A Go program that reads Mermaid flowchart and sequence diagram definitions from a file or stdin and prints them as box-drawing or plain ASCII art. Options control spacing, padding, maximum width, and edge styles such as dotted, thick, and labeled arrows. It also includes a small web interface for rendering diagrams interactively. Developers use it to preview diagrams in a shell, embed them in plain-text docs, or view them over SSH without a browser.
