Abstract 
This paper describes a design framework for representing social-spatial data on maps and diagrams and then illustrates the design approaches for representing social data in two applications. One derives from a project which compared social relationships, organisational structures and social networks of organisational members. The second project produced visualisation tools to support epidemiological investigations of obesity. The mapping approaches for different types of social data are illustrated with case studies. 

Keywords: visualization, social data, representational design.
