Best of the Tableau Web: February 2021

Hello everybody! It’s time for another monthly look at the most exciting Tableau-related blogs and videos produced by our community in the last month. February was a special month, because we also launched our new Tableau Community Hub—a space dedicated to elevating and celebrating the people, programs, and inspirational work of the community. On the hub you can discover community programs and events, making it easier to figure out how and where you want to engage. Our existing community and those yet to join have so much to share, and the hub is a great platform for your stories, expertise and insights to reach more people. And Best of the Tableau Web is, of course, part of it!

This month, I want to highlight three posts that point to some of the big challenges we face as data communicators: balancing form against function, and how those choices affect accessibility.

Best of the Tableau WebLuke Stanke, Circular Bar Charts: Why you should make them but never share them

Luke Stanke’s post, “Circular Bar Charts: Why you should make them but never share them,” explains the challenge. For clicks and eyeballs, a highly stylized visual (e.g., a circular one) might be the best solution, but for accurate insight, it’s best to stick to the standard charts you can find in Tableau’s Show Me feature. Both paths are valid, depending on your circumstances. Being very conscious about when you need accuracy or eyeballs will help here. For those wanting a beautiful celebration of all things circular, I highly recommend Manuel Lima’s “The Book of Circles.”


Pierre Hansquine, Bar Charts: The Good, the Bad, and the Ugly

Having absorbed Luke’s opinions, one might assume that bar charts are best. Largely, I’d agree. But have you considered the arguments proposed by Pierre Hansquine in his post “Bar Charts: The Good, the Bad, and the Ugly”? Pierre reveals the big danger of aggregating data, which we do every time we use Tableau, without stopping to consider what the disaggregated data may hide. 


Chris DeMartini, A Tableau accessibility journey

Whether you follow the route of seeking eyeballs or accuracy, do you consider if your chart is accessible? Chris DeMartini began a fascinating series, “A Tableau accessibility journey,” where he puts his visuals through screen readers. The results in the first post are fascinating: In auditing his work, one example fails in 7 out of 10 accessibility categories. As the series develops, Chris will focus on fixing existing dashboards to increase success rate, and make his work more accessible.

With that, enjoy Best of the Tableau Web with tips, tricks, inspiration and more produced by the Tableau community.
