Urban space has become increasingly heterogeneous and is often site of negotiation and contestation involving diverse stakeholders, complex processes, and dynamics. The city has always been a setting for social discourse. But it seems to be only since a couple of years that the built environment and its development is regularly subject of heated controversy. This project lies at the intersection of urban transformation, Actor-network theory (ANT), and information visualization. It deploys digital methods and ANT‘s material-semiotic approach to the analysis of an urban controversy.
