Principles

represent design qualities each of our charts should possess.

Our data design principles present guiding standards for how we approach the design of data presentation at WHO. The principles apply to data visualisation (visual charts) but also to other representations of data, including descriptive text, sonification (sound), augmented reality and speech-based interfaces.

Crafted specifically for data.who.int, the principles are based on in-depth research and requirements analysis, specifically targeted towards the unique challenges in communicating public health related data. They are rooted in extensive prototyping and testing with real data sets, user research, and industry best practice. The resulting guidelines provide a long-lasting foundation for current and future representations of data.
