Abstract: How is a web app born? Over the past few months, the creators of Dabble DB have been building a new data visualization product - and enjoying the process immensely. This talk will lead you through the design and evolution of a unique new tool, from the initial idea through all of the mockups, experiments, epiphanies, implementations and re-implementations (in Smalltalk, Java, Ruby, Python, Javascript and ActionScript!), illustrated with screenshots and chat logs from months of collaborative remote development - not to mention an exclusive, detailed first look at one of the coolest pieces of information design you've seen in a while.
