For years it’s been relatively easy to ignite medical controversy with emotional but often anecdotal evidence. TV is a popular format for doing just that. It’s quick, colorful and dramatic and increasingly in high-def and big-screen. Add a well known celebrity or two and the effects can be powerful, long term and hard to refute. Much of that power, however, is changing and will continue to change with large datasets that are freely available online – or soon will be. When we talk about the science of “Big Data” as a new discipline, it’s often the datasets that we’re referencing – and the visualization of those datasets can be equally powerful and dramatic.
