Welcome to Network Canvas!

Most current survey tools are optimized for capturing individual rather than network-level data. Those that do capture network data are often tedious and cumbersome.

Network Canvas is different.

It helps you to capture data about both the individual and their social network through intuitive and engaging touch-optimized interfaces, in a co-production environment. By representing abstract relationships and attributes visually, complex structural data becomes more tangible and simple to capture.

This app is part of a free, open-source suite of tools for the collection of social network data developed through the Complex Data Collective, a registered not-for-profit, and funded by the National Institutes of Health (R01 DA042711). Network Canvas is a collaboration between Northwestern University and the University of Oxford managed out of Northwestern’s Institute for Sexual and Gender Minority Health and Wellbeing.
