Practice-based research projects in design often require students to construct contextual reviews of multiple fields. In this interdisciplinary territory of an emerging academic field, supervisors and students must work jointly to construct a mutually satisfactory outcome and avoid producing a body of dissonant voices. Knowledge and practice precedents must be actively constructed into a coherent map of the research terrain so that the project focus can be foregrounded. While the project-based component of practice-based doctorates is familiar creative territory for design students, balancing this with textual scholarship can lead to loss of focus and unstructured proliferation of sources.The use of two-dimensional visualization strategies, such as mind-mapping, can contribute to clarifying research positions and gaps but has limited capacity to dynamically integrate visual and textual sources. Digital visualization tools can facilitate the mutual student and supervisor organization of knowledge, exploit the visual literacy of design students and respond dynamically to project changes. This article shows how one visual tool may better mediate supervisory dialogues with students particularly in the context of practice-based doctorates of design incorporating project components. Following a review of existing research visualization strategies, I exemplify the potential of a hypertext tool to mediate the supervision and knowledge construction process with two narrative cases of student work.
