Presentation: D3: Data-Driven Delight

Track: Making Sense of Data / Time: Tuesday 15:50 - 16:40 / Location: Store Sal, Musikhuset

D3.js is a JavaScript library for manipulating the DOM based on data. In under three years, D3 has changed the face of dataviz, shaken up the world of web mapping and helped create many beautiful and exciting visualizations. In the "Making Sense of Data" track, this talk covers:

* how D3 addresses the fundamental problem of visualization
* the philosophy behind D3
* using D3's layouts and plugins to make hard problems easy
* D3's powerful geographic features
* practical considerations including browser support, efficiency and reusable code
* the best resources for all stages of D3 development

We'll dive deep into D3's source code, but we'll also take breaks to look at some of the loveliest and most interesting visualizations of the past few years. Whether you're a dataviz newbie or expert, there should be something for you here.
