Abstract or Summary
  • The study of the diversity of multivariate objects shares common characteristics across disciplines, including ecology and organizational management. Nevertheless, experts in these two disciplines have adopted somewhat separate diversity concepts and analysis techniques, limiting the ability of potentially sharing and cross comparing these concerns. Moreover, while complex diversity data may benefit from exploratory data analysis, most of the existing techniques emphasize confirmatory analysis based on statistical metrics and models. To bridge these gaps, interactive visualization is especially appealing because of its potential to allow users to explore diversity data in a direct and holistic way, prior to further statistical analysis. This dissertation addresses the problem of designing multivariate visualizations that support exploration and communication of diversity patterns and processes in multivariate data. To this aim, the dissertation presents design considerations as well as implementation and evaluation of interactive visualizations targeting diversity analysis. The contributing visualization techniques and tools include (1) Diversity Map -- a novel multivariate space-filling representation emphasizing diversity patterns in separate attributes; (2) Ecological Distributions and Trends Explorer (EcoDATE) -- a web-based visual-analysis tool that is built upon the Diversity Map and facilitates the exploratory analysis of long-term ecological data with an emphasis on distribution patterns and temporal trends; and (3) HIST -- a visual representation for communicating team diversity faultlines across multiple attributes that is based on multiple linked, stacked histograms. Further, drawing upon lessons from these designs, this dissertation cross compares analyses of species diversity (ecology), microbial diversity (microbiology), and workgroup diversity (organizational management) and introduces a unified taxonomy of analytical tasks to guide the creation and evaluation of future diversity visualizations. The design considerations, visualization techniques, tools, and task taxonomy are evaluated and refined in empirical user studies involving human participants and subject-matter experts.
