Conceptualizing the interactive structure of visualization tools is critical for successful exploration and analysis. As the prominence of multiple coordinated views in visualization increases, better understanding of coordination becomes more and more important for developing improved coordination models that lead to farther reaching applications of coordination. This paper describes how metavisual exploration and analysis of coordination structure and view layout in DEVise visualizations evolved from hand-drawn diagrams to custom-coded software to two Improvise visualizations. The coordination and visual abstraction models implemented in Improvise can be clearly traced back to earlier models implemented in DEVise.
