3 I Want It Now Data Visualization with Power View Historically, users have been constrained to consume data in fixed platforms, with one specific dimension for digital viewings and a couple of printed layouts. Nowadays, with the ubiquitous mobile devices available, Management expects to know key business indicators and day-to-day operation performance on the go. Using well-designed data models and visualization techniques, Power View can leverage timely and quick dashboards for analysis on the go. This session will discuss how to design the appropriate data model to enable self-service data exploration and insightful analysis in Power View, and how to create pixel perfect visualization for mobile devices. You will also learn how the techniques differ from traditional platforms. Using live demo, we will walk through ways to channel users focus on actionable analytics.
