## What it is
vis-timeline is a JavaScript library for rendering fully customizable, interactive timelines and 2D graphs in the browser. It supports items with single dates or start/end ranges, drag-and-zoom navigation, and automatic time-axis scaling from milliseconds to years.

## Use cases
- visualize events on an interactive timeline in a web app
- create a zoomable gantt-style chart with date ranges
- plot time-series data on a 2D graph
- let users create, edit, and delete timeline items
- display project schedules or historical events with pan and zoom

## When to choose
- you need an interactive, customizable timeline or time-based chart in the browser
- you want drag/zoom navigation with automatic time-axis scaling
- you need editable timeline items with two-way data binding

## When to avoid
- you need static, non-interactive chart images
- you need general-purpose charts like bar or pie charts (use a general charting library)
- you need server-side rendering of charts
