It’s been about eight months since we announced d3.chart, and today we’re excited to release a new version of the framework for creating reusable visualizations. We’ve strived to incorporate as many of the lessons we learned in the eight months since the initial release. For detailed explanations of these changes, see our migration guide and […]

One of my favorite things about programming in node is the package management system. In almost all instances, the practice of locally installing modules for each project has simplified my life as a developer. However, as a long time contributor to Grunt, I have become intimately familiar with one edge case where this practice breaks […]

Software development is a lot like meeting a friend for dinner. I’m serious! Every now and then I find myself sitting at a restaurant bar at 6:58 waiting for my friend to show up for our 7 o’clock reservation. All of a sudden I get a text: “Running 5 minutes late. See you soon.” Well, […]

If you’re unfamiliar with recursion, fixed point combinators or the “Y combinator”, take a look at the Wikipedia article and […]

Translating data visualization to smaller resolutions is a challenge that can’t be solved with responsive design techniques alone. New interaction models and different visualization techniques are required to accomodate smaller interfaces. We’ve spent a lot of time thinking about this problem as part of our consulting work and are very excited to be one of […]

In the world of web design it’s more common to condemn or praise existing work than it is to talk about the actual process of creating something great. For example, over the years I’ve complained more and more about restaurant websites. I don’t just mean the ones that play background music, rely on Flash, use […]

HTML5 is ready for mobile Open Web games. Flash is absent or disappearing on mobile devices. Meanwhile, in the US and the UK, 20% of Internet users are mobile-only, and in some markets more than half of Internet users are mobile-only. It is widely held that the next two billion people coming online in the […]

AMD (short for Asynchronous Module Definition) is a JavaScript API specification for structuring modular code. The web abounds with blog posts illustrating its use in front-end application development (and there’s plenty of healthy debate around its necessity, too). The topic of unit testing (despite being integral to the process of software development) does not receive […]

For a recent consulting project I was attempting to render some fairly complex skeletal animations in WebGL on Firefox and Chrome. I quickly ran into a situation where the animation was rendering on Linux and Mac computers, but not on Windows. All the test machines had up-to-date graphics drivers, but the Windows machines threw a […]
