Dan is the master! As one of the longest and most steadfast partners of Tableau he has seen all the use cases and solved all the business challenges presented by users. And, he has brought them all together in this one book to help the rest of the future Tableau users gain the same insight and capabilities. Dan is articulate and thorough in his explanations and hand-holding to make all visualizations and analyses easy and understandable. He is not the master of deception – it is easy – but may not appear so when just beginning. With Dan holding your hand, you will become a pro (and have fun) in no time.
