## What it is
GraphView is an Android library for programmatically creating zoomable and scrollable line, bar, and point graphs with support for multiple series, legends, custom labels, and realtime data updates. It integrates as a simple Android View via Gradle.

## Use cases
- draw line charts in an android app
- create zoomable scrollable bar graphs on android
- show realtime updating sensor data graph
- plot multiple data series with a legend
- add a chart view to an android layout
- display live graph with second y-axis scale

## When to choose
- you need a lightweight, easy-to-integrate chart view for native Android
- you want touch gestures for zooming and scrolling through graphs
- you need realtime/live updating plots or multiple series with legends

## When to avoid
- you need charts on platforms other than Android
- you want a heavily maintained library with active development
- you need advanced chart types like pie, radar, or 3D charts

## Facets
- artifact type: library
- maturity: maintenance
