## What it is
Envision.js is a JavaScript library for building fast, interactive HTML5 charts and visualizations in the browser. It ships with pre-built templates like TimeSeries and a flexible API for composing custom visualizations from detail/summary chart components.

## Use cases
- render interactive time series charts in the browser
- build detail and summary linked charts with zoom selection
- create custom HTML5 visualizations from chart components
- add touch-friendly charts to mobile web pages
- visualize multiple data series with interactive selection

## When to choose
- you need lightweight, dependency-bundled interactive charts for legacy browsers including IE6
- you want pre-built time series templates with detail/summary views
- you need touch and mobile support in a plain JavaScript charting setup

## When to avoid
- you need a maintained library with recent updates and modern tooling
- your project uses modern frameworks like React or Vue with existing chart ecosystems
- you require advanced chart types beyond basic line/time series visualizations

## Facets
- artifact type: library
- maturity: abandoned
- function: data-visualization, charts
- domain: data-visualization, web-development, frontend
