A grammar of data visualization and Flutter charting library based on The Grammar of Graphics.
Graphic is a Flutter charting library that implements a grammar of data visualization based on Leland Wilkinson's *The Grammar of Graphics*. It allows developers to create flexible, interactive charts through declarative specifications rather than being limited to predefined chart types. The library provides customizable mark shapes, data processing composition, and built-in animation capabilities.
Flutter developers who need to build complex, interactive data visualizations in their mobile or cross-platform applications, particularly those who value declarative and flexible charting approaches over rigid templates.
Developers choose Graphic for its balance between theoretical visualization grammar and practical implementation, offering unparalleled flexibility in chart creation through declarative composition, rich interactivity features, and smooth animations not found in simpler charting libraries.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Enables free composition of data processing steps and mark shapes, not limited to predefined chart types, as stated in the README's key features.
Supports event and selection definitions for interactive elements like highlighting and tooltips, demonstrated in the example GIFs showing selection channels.
Allows configuration of mark transition animations with various entrance forms, as highlighted in the animation examples and features list.
Shape draw methods are customizable, providing control over visual elements beyond standard charts, per the README's description of flexible grammar.
Requires understanding of Grammar of Graphics concepts, which can be daunting for developers new to declarative visualization theory, despite the library's aim for practicability.
The README emphasizes using an AI skill for coding assistance, suggesting traditional documentation might be less comprehensive or a secondary priority for users.
Compared to established Flutter charting libraries, Graphic has a smaller community and fewer third-party resources, which could slow down troubleshooting and adoption.
