What is a Gantt chart?
A Gantt chart is a horizontal bar chart that maps tasks against time, showing what needs to happen, in what order, and how long each piece takes. It was developed by Henry Gantt in the early 1900s as a production scheduling tool, and became one of the most widely adopted project management frameworks in history.
In Mermaid, Gantt charts are defined in plain text, so they’re easy to update as timelines shift and plans evolve, without reformatting a spreadsheet or rebuilding a slide.
