Interactive Data Visualization in Qualitative Research Mark Homey College of Education University of Oregon Eugene, OR 97403 (503) 346-2679 Email: mhorney@oregon.uoregon.edu Qualitative researchers analyze data taken from a variety of sources towards the purpose of understanding how and why people do what they do. These researchers almost always gather this data in the form of text: field notes, interview transcripts, transcribed video and audio tapes, archival records, etc., and then analyze it through various coding and categorizing procedures (LeCompte, Millroy, & Preissle, t992). Until the recent development of computer programs to support this process (see Fielding & Lee, 1991), qualitative data analysis had always been a manual operation involving the cutting, pasting, sorting and reviewing of hundreds of text fragments a few at a time. Even with this software support, qualitative researchers still suffer from acute difficulties in visualizing and representing relationships among data and so in distinguishing and communicating which are the most meaningful. Fortunately, this too is being changed by the new software. Figure 1 shows a "data map," an interactive graphic created with a hypertext editing program called EntryWay (Horney, 1992). Beyond the basic coding and sorting operations, programs such as EntryWay also include functions
