Abstract
This presentation introduced nonbinarity, a conceptual and visual framework for the datafication of mixed social identities. Central to the project are the Identity Diamonds, data-driven visualisations that stage identity as a semantic plane of coexisting axes rather than as fixed categorical essences. As critical design artefacts, these diagrams subvert binary logics by translating nominal categories into ordinal variables, producing a continuous field of mixed possibilities. While intersectionality maps overlapping oppressions across fixed categories, nonbinarity challenges the stability of those categories themselves, rendering them fluid, spectral, and coexistent. Situated within data feminism, the work foregrounds the political stakes of representation in data systems, offering alternative infrastructures capable of sustaining fluid, residual, and mixed identities as socially valid and politically actionable.
