## What it is
Morris.js is a lightweight JavaScript library for drawing pretty time-series line, bar, area, and donut charts in the browser, built on jQuery and Raphael.js. It offers a very simple API but is no longer actively maintained.

## Use cases
- draw time-series line graphs in the browser
- add simple bar and area charts to a web page
- render donut charts with a minimal API
- visualize time-based data with pretty defaults
- quickly chart data on a dashboard without heavy charting libraries

## When to choose
- you need simple, attractive line/bar/area/donut charts with minimal setup
- your stack already includes jQuery and Raphael.js
- you're maintaining a legacy project that already uses Morris.js

## When to avoid
- you need active maintenance, bug fixes, or new features
- you want a modern charting library without jQuery/Raphael dependencies
- you need advanced interactivity, zooming, or large-dataset performance

## Facets
- artifact type: library
- maturity: maintenance
- function: data-visualization, charts
- domain: data-visualization, frontend, web-development
- platform: browser
- tags: line-charts, bar-charts, donut-charts, jquery, raphael, time-series, unmaintained, javascript
