Gantt Chart Builder

Turn a project schedule into a clean matplotlib Gantt chart — colour-coded groups, completion overlays, and a today reference line — with one call.

How to use it

Point the agent at a CSV (or table) with a phase/task column, a start date, and either an end date or a duration in days. For example:

“Make a Gantt from assets/sample_schedule.csv, colour by Project, show % done, and draw today’s line.”

Or call the toolkit directly:

from gantt import gantt
gantt("schedule.csv", phase="Phase", start="Start", end="End",
      group="Project", completion="PctDone", today=True,
      title="Project Schedule", out="gantt.png")

What you get

• Horizontal bars ordered as in your data
• Optional group colour-coding and completion hatch overlay
• Auto-scaled date axis (weekly / monthly / bi-monthly)
• PNG output at 150 DPI by default

See references/cheatsheet.md for the full parameter list and CLI examples. Try assets/sample_schedule.csv for a ready-made demo.
