## What it is
Graphic is a Flutter charting library implementing a declarative grammar of data visualization based on Leland Wilkinson's The Grammar of Graphics. It supports composable marks and transforms, interactive selections and events, and mark transition animations across Android, iOS, web, and desktop.

## Use cases
- render charts in a flutter app
- build interactive bar and line charts in dart
- grammar of graphics visualization for flutter
- add tooltips and selection to flutter charts
- animate chart transitions in flutter
- create custom chart shapes beyond predefined chart types

## When to choose
- you are building a Flutter app and need flexible, declarative charts
- you need interactivity like tooltips, crosshairs, and coordinate scaling
- you want custom marks and animations rather than fixed chart types

## When to avoid
- you need charts outside Flutter (e.g., React, Vue, or server-side rendering)
- you want a simple plug-and-play chart widget with minimal configuration
- you need a mature ecosystem with extensive third-party examples

## Facets
- artifact type: library
- maturity: active
- function: data-visualization, charts, ui-components
- domain: data-visualization, cross-platform, mobile-development, frontend
- platform: cross-platform
- tags: flutter, grammar-of-graphics, charting, dart-package, declarative-visualization, interactive-charts, animation, mobile, web-server, desktop
