Ganttdown – Convert Markdown task lists into Gantt chart SVGs

Summary: Ganttdown transforms GitHub-Flavored Markdown task lists into color-coded Gantt chart SVGs with dependency arrows. It runs as a single binary with no dependencies, enabling fast, scriptable chart generation directly from Markdown files.

What it does

Ganttdown parses Markdown tasks including dates, assignees, and dependencies, then outputs presentation-ready Gantt charts as SVGs. It validates dependencies and supports CI/CD integration through command-line usage.

Who it's for

Developers who plan projects in code and want to maintain project plans in version control alongside their source files.

Why it matters

It eliminates the need for separate visual planning tools by generating Gantt charts directly from Markdown, keeping project plans diffable, reviewable, and free from vendor lock-in.
