Symbols carry „cultural“ meaning (*) Mentioned without valuation One or more sentences p. 464 «In addition, color can have very different semantics from one culture to the next.»
Visualizations are animated (+) Positive One or more paragraphs p. 467 «VRs [Visual representations] that exhibit movement can effectively illustrate structural, functional, and procedural relationships among encoded information items.»
Visualizations are compact (+-) Ambivalent One or more paragraphs p. 457 «In any given VR [visual representation], the value of the density property exists along a continuum from low to high (e.g., a VR may have a very high degree of density with thousands of encoded entities or a low degree with only a few entities). This value influences an actor’s cognitive processing and visual reasoning with the encoded information (e.g., too many entities can result in perceptual overload and errors in reasoning).»
Visualizations are globally stable (+) Positive One or more sentences p. 467 «In other words, when a VR [visual representation] has no motion it is available for inspection without temporal constraints. This gives actors time to explore a VR at their own pace, which potentially avoids perceptual and cognitive overload.»
Visualizations are specific (+) Positive One or more sentences p. 456 «For instance, research has demonstrated that certain types of VRs are more appropriate for some tasks and activities than for others.»
Visualizations distort usefully (+) Positive One or more sentences p. 467 «Another well-known example involves the famous London Underground map. When introduced, although the map had a low geometric fidelity value, it encoded the topology of the subway network in a manner that facilitated pertinent tasks. It is reported that people found the map much more useful than the previous map that had a higher geometric fidelity value, as they did not require a high geometric accuracy value for the types of activities they were performing…»
Visualizations make data accessible (+) Positive One or more sentences p. 456 «Such interfaces communicate and provide access to information through visual representations»
Visualizations re-represent structures (+) Positive One or more sentences p. 470 «For example, when trying to solve a problem, changing the representational form of the information space can sometimes trigger apprehension of a solution.»
Visualizations re-represent structures (+) Positive One or more sentences p. 465 «Indeed, studies have shown that adjusting the configuration of information representations has a significant positive effect on the performance of cognitive activities.»
Visual statements show invisibles (+) Positive One or more sentences p. 460 «As digital information is not directly visible to actors, it is only through the representation space that actors access, interact with, modify, or insert information into the underlying information space.»

(Visualizations help overcome cognitive biases --builds on-> Visualizations are animated) (*) Mentinoed One or more sentences p. 467 «Additionally, movement within a VR [visual representation] can make spatial information and depth order salient, reduce spatial ambiguities, and help overcome perceptual and cognitive biases that can be acquired from static VRs.»
(Visualizations reduce effort --builds on-> Visualizations are open for interaction) (*) Mentinoed One or more sentences p. 460 «Static representations do not readily share in and distribute this temporal and dynamic processing of information, and thus force more of the processing load onto internal mental processes.»
(Visualizations are globally stable <-needs to be traded off against-> Visualizations are animated) (*) Mentinoed One or more paragraphs p. 467 «Dynamism ranges in value from zero (i.e., all encoded information items are static) to high (i.e., all encoded information items are in motion).»
