The most-effective visualizations capitalize on the human facility for processing visual information, thereby improving comprehension, memory, and inference. Such visualizations help analysts quickly find patterns lurking within large data sets and help audiences quickly understand complex ideas. Over the past two decades a number of books10<http://cacm.acm.org/magazines/2011/4/106586-design-principles-for-visual-communication/fulltext#R10> ,15<http://cacm.acm.org/magazines/2011/4/106586-design-principles-for-visual-communication/fulltext#R15> ,18<http://cacm.acm.org/magazines/2011/4/106586-design-principles-for-visual-communication/fulltext#R18> ,23<http://cacm.acm.org/magazines/2011/4/106586-design-principles-for-visual-communication/fulltext#R23>have collected examples of effective visual displays. One thing is evident from inspecting them: the best are carefully crafted by skilled human designers. Yet even with the aid of computers, hand-designing effective visualizations is time-consuming and requires considerable effort. Moreover, the rate at which people worldwide generate new data is growing exponentially year to year. Gantz et al.5<http://cacm.acm.org/magazines/2011/4/106586-design-principles-for-visual-communication/fulltext#R5>estimated we collectively produced 161 exabytes of new information in 2006, and the compound growth rate between 2007 and 2011 would be 60% annually. We are thus expected to produce 1,800 exabytes of information in 2011, 10 times more than the amount we produced in 2006. Yet acquiring and storing this data is, by itself, of little value. We must understand it to produce real value and use it to make decisions. -- Vous recevez ce message, car vous êtes abonné au groupe Google Groupes Cartographie d'informations.
