Visualizing big data: live coding an int...

Ever considered making your dataviz interactive by linking it to a database? Yeah, but then you’re entering a world of pain: authenticating users, writing the SQL code, making your widgets interact with each other… In this talk, I build a new dataviz app from scratch. Using source data representing a couple hundred million rows in an Amazon Redshift database, I show which open source tools are used to create an interactive, secure Javascript app using D3js and OpenBouquet . I demonstrate how much value is provided by connecting a dataviz to raw source data – even if it’s big. I discuss the choice of tools and, by the end, you’ll feel confident about achieving the same results even without any database skills.
