“…Another example is the adjacent usage of treemaps by means of small multiples. It may not inherently render the whole visualization a treemap, although the composition could be labeled a space-filling treemap T S (Scheibel et al, 2016).…”

A treemap is a visualization that has been specifically designed to facilitate the exploration of tree-structured data and, more general, hierarchically structured data. The family of visualization techniques that use a visual metaphor for parent-child relationships based "on the property of containment" (Johnson, 1993) is commonly referred to as treemaps. However, as the number of variations of treemaps grows, it becomes increasingly important to distinguish clearly between techniques and their specific characteristics. This paper proposes to discern between Space-filling Treemap T S , Containment Treemap T C , Implicit Edge Representation Tree T IE , and Mapped Tree T MT for classification of hierarchy visualization techniques and highlights their respective properties. This taxonomy is created as a hyponymy, i.e., its classes have an is-a relationship to one another: T S ⊂ T C ⊂ T IE ⊂ T MT . With this proposal, we intend to stimulate a discussion on a more unambiguous classification of treemaps and, furthermore, broaden what is understood by the concept of treemap itself.

“…For example, the time dimension can be incorporated by distributing multiple maps spatially using small multiples (Scheibel et al 2016;Chen et al 2017). Provided the evolution over more than just two states is already analyzed and available by means of trend data, natural metaphors such as physical-based material degradation or shininess can be an effective tool for communication (Wu ¨rfel et al 2015).…”

Treemaps depict tree-structured data while maintaining flexibility in mapping data to different visual variables. This work explores how changes in data mapped to color can be represented with rectangular 2.5D treemaps using procedural texture patterns. The patterns are designed to function for both static images and interactive visualizations with animated transitions. During rendering, the procedural texture patterns are superimposed onto the existing color mapping. We present a pattern catalog with seven exemplary patterns having different characteristics in representing the mapped data. This pattern catalog is implemented in a WebGL-based treemap rendering prototype and is evaluated using performance measurements and case studies on two software projects. As a result, this work extends the toolset of visual encodings for 2.5D treemaps by procedural texture patterns to represent changes in color. It serves as a starting point for user-centered evaluation. Graphical abstract
