Developing reusable visualization components using D3 and Backbone
This session will step through a process for creating components for standards-based Web content, focusing in particular on the creation of common building blocks for data visualization in JavaScript. D3 is an increasingly popular choice for developing visual content and we will look at how items ranging from simple bar charts to custom graphics can be packaged up for easy reuse. Backbone is a widely used toolkit for creating browser-based applications and we will examine how its models and views can play a role in the creation of components. Consideration will be given to combination, customization and the power of reuse versus the perils of over-generalization. https://github.com/rflow/nicar-13-examples/blob/master/slides.key

The Elaboration Model is a systematic method for analyzing the effects of other variables on an initially significant relationship. Overall, it gives journalists a better understanding of how and why the initial relationship works and how other variables affect it. Many variables are likely to affect a relationship in social science, and the model helps journalists assess their effects.
