What the experts are saying? “Visualization doesn’t happen on a page or on a screen. It happens in the viewer’s brain” – Robert Spence “Fundamentally, Data Visualization is not about technology but about Questions and Answers” – Jeff Heer “More often than not, the presentation of quantitative information fails to communicate information clearly and efficiently” – Stephen Few “If no one remembers the numbers then you have not communicated” – Robert Kosara “By visualizing information, we turn it into…a sort of information map. And when you’re lost in information, an information map is kind of useful. ” – David Mc. Candless “Most dashboards…deliver only a fraction of the insight that is needed to monitor the business. ” – Stephen Few Power. BIWorld. Tour. com #PBIWorld. Tour
