InformatIon vIsualIzatIon, self-ethnography and you
an introduction to information Visualization, including a (very) brief history, recent trends and the notion of data Literacy.
Practical application: self-etnography, also known as personal data logging. easily available tools, relevant existing projects and suggested practices.
» the practice of interpreting data and presenting it visually in ways that bring to light patterns of information, so as to enable the discovery of knowledge.
» Visualization is often seen as a way of convincing an audience. But is also a powerful for discovering new knowledge.
» the aim of visualization is to reveal (Manuel Lima)
InformatIon vIsualIzatIon
» History: Maps are as old as written culture. infoviz as we know it dates back to late 1700s.
» almost all common chart types were pioneered before 1810
» early heroes: William Playfair, charles Minard, florence nightingale
Willam Playfair statistical Breviary (1801)
generally considered the first pie chart
Willam Playfair trade balance, england and denmark / norway
florence nightingale, 1858 causes of mortality in the army
charles Minard, 1869chart of napoleon’s disastrous march on Moscow
simultaneous display of multiple variables (location, troops, temperature)
Computers & vIsualIzatIon
» a computer = a machine that computes. computers are number crunchers, perfect tools for visualizing data.
» Modern visualizations deals with huge data sets: - Mri scans - internet topology - Human genomes - social network interactions
Visible Human Project, 19943d data set of the human body
Male: 1 mm slices, 15 gB data female: 0.33 mm slices, 40 gB data

» computational design applies computational solutions to design tasks.
» designers working with code are coming up with new ways of looking at data.
» Visualization realized as software processes allows for new types of visualization. instead of static diagrams, visualizations become interactive interfaces.
» Wikipedia: ethnography (greek ethnos = folk/people, graphia = writing) research strategy often used in the social sciences [..] it is often employed for gathering empirical data on human societies/cultures. data collection is often done through participant observation, interviews, questionnaires, etc. ethnography aims to describe the nature of those who are studied [..]
