Timeline Creator

This generates standalone HTML files with Gantt-style timeline visualizations for project roadmaps and schedules. You get horizontal bars showing task durations, milestone markers, phase groupings (quarterly or custom), and progress indicators with color-coded status states. It calculates duration percentages automatically and uses a clean, responsive layout with semantic colors for done, in-progress, and planned items. Good for when you need to visualize a project schedule quickly without pulling in a heavy charting library. The HTML is self-contained and uses basic CSS, so you can open it in a browser immediately or tweak the styling without much ceremony.
