Introduction#

In this book, we describe a new version of Draco. Draco was first published in [MWN+18].

Draco has three parts.

  1. A general description language for visualizations as facts. Learn more about how Draco describes visualizations.

  2. A knowledge base as constraints over facts. This knowledge base describes which visualizations are valid and what visualizations might be preferred.

  3. An API to use the Clingo solver to apply the knowledge base to visualizations described as a set of facts. Go to the API docs.

The code for Draco is available as open source on GitHub.

If you use Draco, please cite our award winning paper:
