In this keynote talk, Ben Fry discusses principles of graphics design and of dynamic visualization that can improve the insight gained from data. He also presents a range of visualizations of genetics data he has created, some of which have been used to improve tools used by biologists, some of which has been exhibited in art galleries and in Hollywood movies. He also presents 'Processing', a computer language he co-developed that can easily create dynamic visualization of complex data. This talk was part of VIZBI 2010, the EMBO workshop on visualizing biological data (vizbi.org). This video has been filmed and distributed with permission under a creative common license.
