## What it is
Core Plot is a 2D plotting framework for macOS, iOS, and tvOS written in Objective-C. It is highly customizable and capable of drawing many types of plots, distributed via CocoaPods, Carthage, and Swift Package Manager.

## Use cases
- draw line charts in an iOS app
- plot bar graphs on macOS
- add customizable 2D plots to a tvOS application
- render scatter plots in a Cocoa app
- create scientific data visualizations on Apple platforms

## When to choose
- you need highly customizable 2D charts in a native Apple-platform app
- you are building with Objective-C or Swift on macOS, iOS, or tvOS
- you need a mature, permissively licensed (BSD) plotting library

## When to avoid
- you need charts for Android, web, or Windows
- you want 3D plotting
- you prefer a pure Swift library with modern Swift APIs

## Facets
- artifact type: library
- maturity: stable
- function: data-visualization, charts
- domain: data-visualization, apple-ecosystem, graphics
- platform: cross-platform
- tags: cocoa, objective-c, plotting, 2d-charts, tvos, swift-package-manager, macos, ios
