Dataviz Design Principles

Dataviz Design Principles is an interactive web-based game designed to help users improve their understanding of design principles in data visualization. The tool presents pairs of charts and asks users to select which version looks better, aiming to develop a sharper design sense by highlighting key concepts that influence the clarity and professionalism of a chart. The game was created by Yan Holtz in collaboration with Diana MacDonald, whose charts serve as the foundation for the visual comparisons, with intentional design degradations introduced to illustrate common pitfalls.

The platform is structured as a series of image-based choices, where users can click or press keyboard keys to select between alternatives. The experience is modeled on the idea that learning to recognize effective design comes from exposure to both strong and weak examples. The game emphasizes the importance of design in making data visualizations appear polished and trustworthy, addressing the challenge of teaching what constitutes a clean or professional chart. It is intended as a supplement to other data visualization learning resources, especially for those who have already grasped the fundamentals but wish to refine their design judgment.

The tool is positioned as an educational resource for individuals interested in data visualization, including students and professionals seeking to enhance their ability to evaluate and create effective charts. The creators encourage feedback and suggestions for expanding the game to cover additional design rules, indicating that the project is actively maintained and intended to grow over time.
