Drawing on ethnographic studies of (landscape) architects at work, and interdisciplinary cooperation with them, this paper presents a human-centered approach to information visualization. A 3D collaborative electronic workspace allows people to configure, save, and browse arrangements of heterogeneous work materials. A network of links between parts of documents and objects underpins this spatio-temporal order. Both spatial arrangements and links are created and maintained as an integral part of ongoing work with the ‘live’ documents and objects that populate these arrangements. The result is an extension of the physical information space of the architects’ studio that utilizes the potential of electronic data storage, visualization, and network technologies to support work with information in context.
