Far from being the enemy, data can be a designer’s best friend. So much so that it just might be the backbone of the next evolution of web design. Data doesn’t mean less creativity and experimentation, it means more. We’ve learned how to design sites that look good, and we know how to mark up our pages with web standards. Now it’s time to figure out what performs best.
In this session you’ll learn not just the fundamental concepts of this ‘new web design’, but how you can get started with data-driven design using free tools that are available right now. If you’ve reached a point where you know how to design and build attractive, standards-based web sites and are wondering what comes next, this is the session for you.
