In plain English

Charts is a library for drawing charts and graphs inside Apple apps, iOS on iPhone and iPad, tvOS on Apple TV, and macOS on the Mac. The description calls it "the Apple side of the crossplatform MPAndroidChart." MPAndroidChart is a popular charting library for Android by Philipp Jahoda, and this project is a Swift port that gives Apple developers the same set of charts with the same general API, so a team that already builds for Android can produce very similar-looking charts on Apple platforms without learning a completely different tool. Both Swift and Objective-C projects can use it, and the demo app is written in Objective-C to show that. Starting with version 5.0 the library was renamed from "Charts" to "DGCharts" to avoid name conflicts with Apple's own newer Swift Charts framework. The README highlights this as a breaking change and points readers at migration notes. It is distributed as an embedded framework and can be installed in several ways: CocoaPods with pod 'DGCharts', Carthage with prebuilt binaries, or Swift Package Manager by adding the GitHub URL as a dependency. There is also an optional companion package called ChartsRealm for integrating with the Realm.io database, kept as a separate dependency so you only link it if you need it. Third-party bindings exist for Xamarin. Supported platform versions listed are iOS 12.0 and up, tvOS 12.0 and up, and macOS 10.13 and up, with the master branch targeting Xcode 14 and Swift 5.7. The README also includes troubleshooting notes about Bridging Headers when mixing Swift and Objective-C, and links to many community tutorials and blog posts covering line charts, bar charts, radar charts, and SwiftUI integration. You would reach for this library when you are building an iOS, tvOS, or macOS app that needs to display non-trivial charts, especially if you already use MPAndroidChart on Android and want a consistent experience across both platforms. The full README is longer than what was provided.
