InfoVis: The Landscape Metaphor
InfoVis: The Landscape Metaphor beskriver datavisualiseringar med hjälp av landskapmetaforen.
Whoever that has followed a driving course is able to catch the meaning of a traffic signal in a fraction of a second. Nevertheless if we show the same signal to someone that hasn't been taught how to interpret it or has never seen one, it will be very difficult for him or her to get the meaning in its complete magnitude, even if staring for a long time in front of it trying to decipher it ... In the end, it seems that decoding a map, be it spatial or thematic, results quite natural for most of the human beings, requiring just very little training. This doesn't appear to be the case with more recent developments of more abstract nature, like parallel coordinates or hyperbolic geometry, just to mention a couple of examples. ... The landscape metaphor, and spatialisations in general, constitute very attractive ways of representing big amounts of data in an intuitive way. The notions of distance and height are easily understood by many people, even when they encode other variables like similarity, density, or prevalence of a certain term.
En av de tekniker som beskrivs är Islands of Music (Matlab-kod finns att tillgå):
Islands of Music are a graphical user interface to music collections based on a metaphor of geographic maps. Islands represent musical genres. Mountains and hills on these islands represent sub-genres. The islands are situated in such a way that similar genres are close together and might even be connected by a land passage while perceptually very different genres are separated by deep sea. The pieces of music from the collection are placed on the map according to their genre. To support navigation on the map the mountains and hills are labeled with words which describe rhythmic and other properties of the genres they represent.
