## What it is
JBChartView is Jawbone's iOS charting library for line and bar graphs, built as drop-in UIView subclasses in Objective-C. It uses a UITableView-style data source and delegate pattern and supports expand/collapse animations.

## Use cases
- draw line charts in an iOS app
- render bar graphs on iPhone and iPad
- add customizable charts to a UIKit app
- create animated expand/collapse charts
- build sparklines for user activity data
- use a UITableView-style charting API in Objective-C

## When to choose
- you maintain a legacy Objective-C iOS app needing simple line or bar charts
- you want a lightweight drop-in UIView chart with UITableView-like protocols
- you need expand/collapse chart animations without heavy dependencies

## When to avoid
- you are starting a new Swift project and want actively maintained charts
- you need advanced chart types like pie, scatter, or interactive charts
- you require ongoing updates and modern iOS version support
