Information Representation and Visual HCI

             .
             It is easy enough to decorate this data without lying.
             The wages graph is narrower than the inflation rate graph; this distorts the appearance making the wages line look steeper even if both where falling at the same rate. This is false representation and distorting what the data has to say. .
             Finally the most basic error made is that the graph has been labelled incorrectly. It is the wages gains that are declining and NOT the Wages, which will also confuse the viewer and there perception after analysing the information. .
             This graph would be seen in a newspaper or tabloid to show their audience the state of the economy or to prove a point against an organisation or government. It is a simple diagram, which isn't interested in showing a truthful representation of data that is probably why it contains so much chartjunk. .
             Lurking behind the chartjunk is the information the audience seeks. Decorations frequently distort data and will never salvage the underlying content. The way the data has been manipulated suggests that it out to prove a point and sway the audience's perception of this problem.
             Good example - Underground Tube Map.
             .
             The above diagram shows a good example of information representation in the form of a map. The map is distributed in a small 7x15cm leaflet that opens up into the above map. It shows an overview of the London Underground Tube map and the lines and stations it provides. This image is clear, precise and very efficient as its shows a large amount of data presented in a small place. The viewer has a .
             1. Legend to refer to determine what line he/she will need to take, also a key to the symbols used in the map.
             2. Each station name at each stop has been included and changeovers.
             3. Train Stations are clearly visible and Heathrow Airport.
             4. The River Thames has been included to encourage the viewer to relate the Underground map to a map of London.
             The map has efficiently made large data set seem coherent and used information graphics effectively, promoting ease of use and clarity.
