NYTimes: the pace car
The New York Times’ ebola visualization sets the bar for high quality interactivity.
That makes sense as Mike Bostock works at the Times. He is one the creators of D3.js which is the open source engine behind most of the gorgeous data-driven visualizations on the Web these days. If you have not yet seen it, the D3.js examples gallery is a whole lot of eye candy.
Take this outbreak visualization as confirmation that any open-source white label outbreak widget should be based on D3.js.
