Creating Animations and Transitions With D3 For the ambitious, this is a great intro to creating your own animations and transitions in d3.js. If you get in over your head, drop by the Visually Marketplace to hire one of our talented developers. In interactive visualisation, there is the word reactive. Well, maybe not literally, but close enough. The fact is that reactivity, or the propension of a visualisation to respond to user actions, can really help engage the user in a visualisation, and help them understand its results. So I’ll go ahead and state that animation, if done right, can make any interactive data visualization better. How is that? When coupled with interaction, it’s a very useful way to give feedback to the user. That said, animation can definitely ruin your visualization, too. Animation is very prominent. So we’ve seen how animation is helpful in data visualization. The principle If you know how to draw in d3, you almost know how to animate. Animations are called “transitions” in d3 for a reason. How this is done
The world’s top 50 billionaires: A demographic breakdown. Top 50 Billionaire Breakdown If you asked anyone to picture the wealthiest person in the world at any given time, you could bet on some common denominators: probably a man; probably somehow attached to the words “multinational” or “conglomerate”; probably on a yacht off a private island. With Slate’s Top 50 Billionaire Breakdown, we attempt to visualize the richest of the rich by paring them into demographic categories: age, location, industry, source of wealth, education, and religious affiliation. Some of the sortings are heartening: There are more self-made men than born-rich kids in the top 50, and the self-made billionaires’ total wealth is bigger. Some are less so: The entire African continent has the same number of billionaires as Canada (one each), and there isn’t a single woman in the top 50 who’s self-made. Correction, Nov. 18, 2013: The interactive originally mislabeled the Koch brothers as Jewish.
