Draco is a formal framework for representing design knowledge about effective visualization design as a collection of

constraints. You can use Draco to find effective visualization designs or validate existing ones. Draco's constraints

are based on Answer Set Programming (ASP) and solved with the [Clingo](https://github.com/potassco/clingo) constraint

solver. We also implemented a way to learn weights for the recommendation system directly from the results of graphical

perception experiment. Draco v2 is a much improved version of the first iteration of

[Draco](https://github.com/uwdata/draco).

## Documentation

Read about Draco in the online book at [https://dig.cmu.edu/draco2/](https://dig.cmu.edu/draco2/) or launch it in

interactive mode using [Binder](https://mybinder.org/v2/gh/cmudig/draco2/HEAD). In the documentation, we just refer to

_Draco_ without a version.
