Being someone who graduated only last year and working in the Payments Sector primarily in the data visualization space, Aurélien Vautier's, "The Fundamentals of Data Visualization" has changed the way I perceive and approach data visualization. The plain, simple, intuitive, understandable and lucid User Interface concerning all the content present in the package hits all the right spots and delivers the learnings so well. Recommend for all people in the data viz space. It's the small things and attention to detail, and I'll tell you these things aren't small when you truly understand them in the wider context of your day-to-day work. There are only a handful of people who are authentic, transparent and genuine people who only want to deliver quality content to the community, Aurélien's right at the top of the list. Follow him, and purchase the package contents, it's worth it and you won't regret it!
