Graphic

Graphic is a grammar of data visualization and Flutter charting library.

• A Grammar of Graphics: Graphic derives from Leland Wilkinson's book The Grammar of Graphics, and tries to balance between theoretical beauty and practicability. It inherits most concepts, like the graphic algebra.
• Declarative and Reactive: As is encouraged in Flutter, the chart widget of Graphic is declarative and reactive. The grammar of data visualization is implemented by a declarative specification and the chart will reevaluate automatically on widget update.
• Interactive: With the signal and selection mechanism, the chart is highly interactive. It is easy to pop a tooltip or scale the coordinate.
• Customizable: With the shape and figure classes, it's easy to custom your own element, tooltip, annotation, etc.
• Dataflow Graph and Operators: Graphic has a internal structure of a dataflow graph and operators. That is how the reactive reevaluation and interaction is implemented.
