The WHO Data Design Language (DDL) is a framework for consistently presenting global health data. It provides detailed guidelines and tools to ensure data visualizations, charts, and other visual materials are accessible and effective for diverse audiences.
Key components of the DDL include a library of chart templates, typography and color specifications, and design principles focused on readability and usability. The system emphasizes accessibility by incorporating internationalization (i18n) and accessibility (a11y) standards.
