3. Why Interactive Visualization? Biodiversity databases have become widely available to the public and to other researchers Trees and graphs are commonly used information structures Animal classification, food webs, gene ontology, … Visual representations exploit human visual processing to reduce the cognitive load Better interactive tools are needed for visual data exploration Biodiversity databases have become widely available to the public and to other researchers Trees and graphs are commonly used information structures Animal classification, food webs, gene ontology, … Visual representations exploit human visual processing to reduce the cognitive load Better interactive tools are needed for visual data exploration
