Experiments investigating the worth of such algorithms from the point of view of human usability can take di􀀋erent forms, depending on whether the graph has meaning in the real world, the nature of the usability measurement, and the e􀀋ect being investigated (algorithms or aesthetics) . Previous studies have investigated performance on abstract graphs with respect to both aesthetics and algorithms, 􀀌nding support for reducing the number of crossings and bends, and increasing the display of symmetry.  \nThis paper reports on preference experiments assessing the e􀀋ect of individual aesthetics in the application domain of UML diagrams. Subjects'preferences for one diagram over another were collected as quantitative data. Their stated reasons for their choice were collected as qualitative data. Analysis of this data enabled us to produce a priority listing of aesthetics for this domain. These UML preference results reveal a difference in aesthetic priority from those of previous domain-independent experiments.  \nCommunicated by Michael Kaufmann: submitted April 2001;  \nrevised December 2001 and June 2002 .  \nH.C.

In addition, designers of these algorithms often claim that by conforming to these aesthetic criteria, the resultant graph drawing helps the human reader to understand the information embodied in the graph. However, little research has been performed on the usability aspects of such algorithms: do they produce graph drawings that make the embodied information easy to use and understand? Is the computational e􀀋ort expended on conforming to conventional aesthetic criteria justi􀀌able with respect to better usability? As automatic graph layout algorithms are increasingly being used in information visualisation systems (for example, for the visualisation of social networks or data-􀀍ow diagrams), it is important that thee􀀋ectiveness of these algorithms from a user point of view is investigated, to ensure that the algorithms used are appropriate for the domain being modelled.  \nIn de􀀌ning a framework for experimentation in this area, we identify three dimensions of usability studies investigating the merit of graph drawing algorithms from a human perspective: the nature of the graph (syntactic or semantic), the type of usability measurement (preference or performance), and the e􀀋ect being investigated (algorithms or aesthetics) .  \n􀀏 Syntactic graph drawing experiments use a graph structure that has no meaning in the real world: it is merely an abstract collection of nodes with relationships between them. Semantic graph drawing experiments use a graph within a particular application domain: in this case, the graph has meaning in the real world (for example, a transport network, or a data-􀀍ow diagram), and the experimental tasks are performed in relation to th","cbCaihh6VH6Dz9do","https://ap.wps.com/l/cbCaihh6VH6Dz9do","pdf",463315,25,"English","# Abstract\n# 1 Introduction\n## Usability study dimensions (syntactic vs semantic, preference vs performance, algorithms vs aesthetics) \n## Background from prior syntactic studies\n# 2 Related Work and Motivation","[{\"question\":\"How does the paper define usability studies for graph drawing algorithms?\",\"answer\":\"It identifies three dimensions: the nature of the graph (syntactic vs semantic), the usability measurement type (preference vs performance), and the investigated effect (algorithms vs aesthetics).\"},{\"question\":\"What data does the paper collect in its UML preference experiments?\",\"answer\":\"It collects quantitative data on subjects’ diagram preferences and qualitative data from the subjects’ stated reasons for choosing one diagram over another.\"},{\"question\":\"What distinguishes this work from previous domain-independent studies?\",\"answer\":\"The paper reports UML domain-specific preference results and notes that aesthetic priority differs from that observed in earlier experiments on abstract, domain-independent graphs.\"}]","Graph Layout Aesthetics in UML Diagrams - User Preferences | PDF",63]
