Tableau doesn’t support 3d graphs because they aren’t consistent with best practices for presenting data in a way that it can be accurately understood. Studies have shown that 3D Charts are less accurate than other visualization types, and Tableau has a strong bias towards accuracy in presentation. No one finds 3D bars, 3D pies etc. analytically useful. On the contrary they make the charts harder to read with no real benefit. So many Viz Gurus advised not to use 3D charts in tableau.
Being a field expert and also being humble is a trait that is hard to come by .One name which came to my mind is Curtis Hariss .A well known face across the Tableauverse.His easy to use, creative and intuitive Tableau Vizes benefited so many Tableau authors around the globe.Curtis always turns complex data sets into beautiful, simple diagrams that tease out unseen patterns and connections.
Data security is the main priority for organizations of every size and genre. In simple terms, we can say it’s a practice of keeping data protected from corruption and unauthorized access. The main focus of every organization is to ensure privacy while protecting personal or corporate data.The first step in protecting your enterprise's data privacy and security is to identify the types of information/data you want to protect and where that information is exposed in your organization.
When the idea of collating a list of Tableau books one should read to get an expertise on the tool came up, it seemed fun in the beginning but not for long. We kept spinning ours pens for some time because every book in the market provides a unique blend of knowledge ranging from a beginner to the masters!! The list kept piling up till we gave up.
I recently had the pleasure of interviewing Michael Mixon, a well known Tableau Viz artist, painter, photographer and traveler.I think you all agree Michael's every project/dashboard is created by design. It is thought out, analyzed and finally, designed and executed.His every dashboard communicates a distinct message.Take a look into his story, where he gets inspiration, and how he uses Tableau and learn more about him.
A waffle chart is basically a square version of a pie chart. Since it does not involve angles, it’s easier for the reader to compare accurately .A waffle chart uses a grid of differently colored squares (hence the name) to show proportion instead of pie slices, making it easier for the viewer to cognitively process the various data relationships. A lot of times, these are used as an alternative to the pie charts. It provides visual communication beyond simple data visualization.
