Flutter Graph View

Widgets for beautiful graphic data structures, such as force-oriented diagrams.

Features

TODO:

Data converter: convert business data into graphic view data.
Algorithm: calculate vertex layout.
- Force directed algorithm.
- Random algorithm (In example folder).
Data panel embedding.
Style configuration.
More graphical interactions.
