CHAPTER 11 INFORMATION VISUALIZATION
OUTLINE Scientific Visualization(scivis) Engineering, computational fluid mechanics, mathematics to medical and earth scIences Data coming from numerical simulations and measurements of physical quantities Information Visualization(infovis) More abstract of data Generic graph, trees to database tables, text and computer software Present a succinct overview of inforvis methods and techniques
OUTLINE • Scientific Visualization (scivis) • Engineering, computational fluid mechanics, mathematics to medical and earth sciences • Data coming from numerical simulations and measurements of physical quantities • Information Visualization (infovis) • More abstract of data • Generic graph, trees to database tables, text and computer software • Present a succinct overview of inforvis methods and techniques
OUTLINE 11.2 goal of infovis 11.3 similarities and differences between the scivis and infovis fields 11.4 visualization of the database table 11.5 visualization of relational data 11.6 visualization of multivariate data 11.7 visualization of text document

11.2 WHAT'S INFOVIS? To visualize is to form a mental model or mental image of something" [Spence 071 Broad definition visualization applies to abstract quantities and relations in order to get insight in the data [chi 02 1 Inforvis application a wider spectrum of data types than scivis applications: data that has no physical placement > Abstract data: computer file systems, databases documents from archives, and stock exchange courses
11.2 WHAT’S INFOVIS? ◼ To visualize is to “form a mental model or mental image of something” [Spence 07] ◼ Broad definition: visualization applies to abstract quantities and relations in order to get insight in the data [Chi 02 ] ◼ Inforvis application ➢a wider spectrum of data types than scivis applications: data that has no physical placement ➢Abstract data: computer file systems, databases, documents from archives, and stock exchange courses
