How do analysts think about grouping and spatial operations? This overarching\nquestion incorporates a number of points for investigation, including\nunderstanding how analysts begin to explore a dataset, the types of\ngrouping/spatial structures created and the operations performed on them, the\nrelationship between grouping and spatial structures, the decisions analysts\nmake when exploring individual observations, and the role of external\ninformation. This work contributes the design and results of such a study, in\nwhich a group of participants are asked to organize the data contained within\nan unfamiliar quantitative dataset. We identify several overarching approaches\ntaken by participants to design their organizational space, discuss the\ninteractions performed by the participants, and propose design recommendations\nto improve the usability of future high-dimensional data exploration tools that\nmake use of grouping (clustering) and spatial (dimension reduction) operations.\n
