Yahoo! recently released a dedicated data visualization website [yahoo.com] to highlight their Content Optimization and Relevance Engine (C.O.R.E.), a service that aims to personalize the Yahoo! experience depending on a collection of demographic (e.g. gender and age) and geographic (e.g. cities) variables, in combination with personal interests (e.g. Finance, Sports, Health).
The visualization, developed by Periscopic, allows to explore the relevant content of their homepage according to a set of user-selected parameters, so that one can solve questions like: "What is the most popular story for females between 18 and 24?". The shown content reaches back up to 24 hours ago. Each separate story can be further analyzed in terms of popularity over time, plus its demographic reach of the audience that actually clicked on it. Notably, the floating 3D globe of particles consists of news stories.
