In order to help analysts understand these graphs, researchers have developed and studied a large number of graph visualization techniques. This variety of techniques presents solutions to a breadth of graph analysis tasks, but it introduces a new issue: complexity. The variety introduces both the complexity of comparing techniques in an objective way and the engineering complexity of implementing so many techniques.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EIn my thesis, I present the graph-level operations model (or GLO model) as an elegant solution to these challenges.\u0026nbsp;The GLO model consists of a model of visual elements and a set of functions (GLOs) that manipulate those elements. I further\u0026nbsp;introduce GLOv2, an instance of the GLO model derived from twenty-nine graph visualization seed techniques from literature. I show how to use the model to define graph visualization techniques, including the original seed techniques as well as novel techniques. I demonstrate the analysis potential of the GLO model by clustering the twenty-nine seed techniques using two different GLO-based schemes. Finally, I demonstrate the practical engineering potential of the model through a Javascript implementation (GLO.js) and two applications built atop the implementation for exploring a graph and discovering novel techniques using GLOs (GLO-STIX and GLO-CLI).\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E \u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Graph-Level Operations: A High-Level Interface for Graph Visualization Technique Specification"}],"uid":"27707","created_gmt":"2016-06-30 11:24:42","changed_gmt":"2016-10-08 02:18:15","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2016-07-01T08:00:00-04:00","event_time_end":"2016-07-01T11:00:00-04:00","event_time_end_last":"2016-07-01T11:00:00-04:00","gmt_time_start":"2016-07-01 12:00:00","gmt_time_end":"2016-07-01 15:00:00","gmt_time_end_last":"2016-07-01 15:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
