timevis

Timevis is a lightweight JavaScript library for rendering interactive timelines in web pages. It provides a simple API to visualize temporal data along a horizontal axis, enabling users to scan through time, focus on specific periods, and read item details at a glance. Timevis emphasizes a compact footprint and easy integration into existing web projects.

The library represents data as items and, optionally, groups. Each item typically has an id, content or label, a start time and, optionally, an end time to indicate a duration. Groups can be used to categorize items. A timeline is created by supplying a container element, a data model consisting of items (and optional groups), and configuration options for the time scale, item height, and layout. After initialization, developers can programmatically add, update, or remove items and groups, and can respond to user actions through event callbacks.

Common features include panning and zooming the time axis, automatic layout of items to avoid overlaps, support for custom item content templates, and tooltips or popovers for details. Timevis is designed for web environments without heavy dependencies, making it suitable for dashboards, project planning views, or historical data displays.

In the broader ecosystem, timevis sits among lightweight timeline libraries and competes with more feature-rich tools. It is used when a simple, fast timeline is required with straightforward data binding and minimal configuration.
