Drucker challenges the realist assumptions embedded in conventional data visualisation. Her iconic distinction is between data, understood as given, and capta, understood as taken, selected and constructed through acts of interpretation. The theoretical contribution lies in showing that charts, maps and diagrams do not neutrally display knowledge; they materialise assumptions about certainty, observation and evidence. Methodologically, Drucker performs an epistemological critique of graphical conventions and proposes visual forms capable of registering ambiguity, contingency and observer dependence. The conceptual operation is interpretive redesign: uncertainty must affect the coordinate system itself rather than appear merely as decoration added to an otherwise stable model. The wider bridge reaches digital humanities, critical cartography, information design and visual epistemology. Graphical display becomes a humanistic argument when its formal structure acknowledges that every dataset is already an intervention into the phenomena it claims to represent.
