## What it is
Williamchart is an Android library written in Kotlin for rapidly building attractive charts such as line, bar, and donut charts via customizable XML views. It is lightweight and modular, but the project is no longer maintained.

## Use cases
- add line charts to an android app
- draw bar charts in android
- create donut charts with custom styling
- show data visualizations on android wear
- add tooltips to chart points in android

## When to choose
- you need simple, lightweight line, bar, or donut charts in an Android app
- you want chart views configurable directly through XML attributes
- you are okay using an unmaintained library as-is

## When to avoid
- you need ongoing updates, bug fixes, or compatibility with the latest Android/Kotlin versions
- you need chart types beyond line, bar, and donut
- you require a license file for legal compliance, since no license is specified

## Facets
- artifact type: library
