## What it is
Frappe Gantt is an open-source JavaScript library for rendering interactive, customizable Gantt charts on the web. It supports flexible timeline views (hour, day, year), task dependencies with arrows, drag-and-drop date changes, progress tracking, holiday/weekend handling, and multi-lingual labels with zero dependencies.

## Use cases
- render gantt charts in a web app
- visualize project task schedules and dependencies
- interactive timeline with draggable task bars
- exclude weekends and holidays from task progress
- embed a project schedule view in ERP or PM software
- customizable gantt chart library with no dependencies

## When to choose
- you need a lightweight, dependency-free Gantt chart in a browser-based project
- you want customizable timeline views (hour/day/year) and configurable popups
- you need to mark or ignore weekends/holidays in schedule calculations
- you want drag-and-drop editing of task dates and progress
- you need multi-lingual support for international teams

## When to avoid
- you need full project-management features like resource allocation or critical-path analysis
- you require server-side rendering or a non-JavaScript environment
- you need a complete project management application rather than a chart component
- you need advanced scheduling algorithms beyond visual task dependencies
