Adams, Nate, Music Director, Assistant Program Director has reference to this Academic Journal, PHwiki organized this Journal Seek in addition to You Shall Find Visualization Tools Professor Elaine Ferneley What is Visualization Defn: (vb) to as long as m a mental image or vision of to imagine or remember as if actually seeing Graphic representations of data can be used to make the in as long as mation contained more accessible. The graphical as long as m is easier to investigate than tables of data. It helps the user to search as long as items of interest in addition to to detect patterns. Examples include graphs in addition to bar charts. Cognitive activity it goes on in the mind, creation of an internal model or cognitive map; Internal to the individual human being provides insight in addition to underst in addition to ing; Individuals will interpret visualizations in different ways Visualization Metaphors All attempts to create a representational picture from some in as long as mation are visualization. Sometimes the representation will explain a physical fact e.g. a bar chart as long as the heights of all the children in a class. Sometimes the representation will explain conceptual facts e.g. business processes In as long as mation visualization is different because the mapping is not based on the physicality of the data. All data has a physical as long as m words in a book, documents stored on a hard disk but in order to graphically display the meaning behind the data a new physicality has to be created. This new physical model creates a metaphor to help the user navigate the in as long as mation that is presented to them. In Microsoft Windows, a desktop metaphor supports access to computer files.

A Classic Visualization Individuals all have a unique underst in addition to ing & perspective Minards Map of Napoleons March on Moscow Originally created in 1812 Depicts several variables in a small space: the size of the French army depicted by the width of the b in addition to s; its location on a two-dimensional surface; the direction of the movement of the advance (pink upper b in addition to ) in addition to retreat (black lower b in addition to ); the temperature on certain dates during the retreat. Florence Nightingales Coxcombs to highlight needless deaths during the Crimea War (1854-56) Blue deaths from preventable disease (cholera & typhoid); Red deaths from wounds Grey deaths from other causes Mortality peaked in January 1855 – 2761 died of contagious diseases, 83 of wounds, 324 of other causes. Based on the army’s average strength of 32393, Nightingale computed an annual mortality rate of 1174 per 1000.
Key Visualisation Issues Selection: should all data be represented; can selection take place automatically; Is it useful to suppress in as long as mation. Presentation: How do you lay the data out e.g. Harry Becks distortion of the tube network to make the best use of space in addition to make it more memorable; New issues of how to present on mobile devices. Representation: Colours, lines, slopes, graphs, pie charts etc; Can attributes be combined; How do you represent many attributes (>20 ). Scale: How to cope with vast quantities of data abstraction. Rearrangement, interaction in addition to exploration: Can the user view be changed; Is it possible to explore the underlying datasets. Rearrangement the key to insight Simple example as long as illustration: 10 crops e.g. rice, cereal, barley, corn etc.; 7 treatments e.g. fertiliser, insecticide, pruning etc.; Result of treatment noted: Purple = improvement; White = degradation. 10 crops, rice, barley, corn 7 treatments: fertiliser, insecticide, pruning Rearrangement the key to insight 1 3 8 2 6 10 4 7 9 5 A B C D E F G 10 crops, rice, barley, corn 7 treatments: fertiliser, insecticide, pruning

Current search engines are seen as analytical, methodical, serial technologies suited to the activities of the left hemisphere of the human brain. Shapes in addition to patterns have been ignored by the text based approach in addition to would tap in to right hemisphere activity. Bad displays of data obviously make perception much more difficult as long as people. The layout of the voting cards in some US states was seen as the main reason why the whole 2000 election was thrown into turmoil because the poor representation of in as long as mation actually hampered peoples decision making capabilities. US Voting 2000 Why we have Bush
US Voting Why we have Bush US Voting Errors associated with the design of the Palm Beach County ballot were primarily due to poor ballot layout, resulting in problematic spatial mappings. The two-page as long as mat of the ballot violated the expectations of voters. People reading English text read from left to right in addition to will read a left-h in addition to page from top to bottom be as long as e reading a right-h in addition to page. Thus, the natural behaviour as long as voters was to start at the top of the left-h in addition to page in addition to read down. However, holes on the ballot book corresponded in alternating fashion to c in addition to idates on the left in addition to right pages. Some voters claimed to be confused in addition to said that they wanted to vote as long as the second c in addition to idate from the top left (Gore) but punched the second hole, which actually corresponded to Buchanan, who was listed on the right-h in addition to page Is this Possible
Focus on the dot in the centre in addition to move your head backwards in addition to as long as wards Are the purple lines straight or bent Do you see grey areas in between the squares Where did they come from
You should see a mans face in addition to a word This is not animated! Relax in addition to concentrate on the 4 small dots in the middle of the picture as long as 40 secs Then, take a look at a wall near you (any smooth, single coloured surface) You will see a circle of light developing Start blinking your eyes a couple of times in addition to you will see a figure. Who do you see

DaVincis The Last Supper What do You Feel What do You Feel
What do You Feel What do You Feel Visualization in addition to Large Datasets It is hoped that the previous experience of the user will help them with the new, abstract in as long as mation. Investigating the semantics of data means creating links in addition to classifications regardless of physical boundaries in addition to it is these semantic connections that can be given a graphical representation. The aim of in as long as mation visualisation is to provide a computer-based, interactive graphic of abstract data which improves cognition As an alternative to a search on the internet returning a text list, a graphical representation can show the links between sets of concepts. The aims are to allow the user to find what they need faster in addition to to identify previously unrecognized relationships.
Summary Visualisation is not a new discipline
