Bottom-up vs. Top-down Trade-offs in Efficiency, Understanding, Freedom and Creativity with InfoVis Tools

About



We present a qualitative study comparing people's visualization processes using two visualization tools: One promoting a top-down approach to visualization construction (Tableau Desktop) and one implementing a bottom-up constructive visualization approach (iVoLVER). Our results show how the two approaches influence: 1) the visualization process, 2) decisions on the visualization design, 3) the feeling of control and authorship, and 4) the willingness to explore alternative designs. We discuss the complex trade-offs between the two approaches and outline considerations for designing better visualization tools.
