Critiquing other people’s Tableau visualisations

Tableau dashboard with and without design

Tableau’s sample files wouldn’t look so good if they weren’t well designed

Alistair Knock posted a great question by Moose Peterson on Google+  about feedback on user photographs on the web:why do most people just make anodyne comments along the lines of “Nice!” when they probably have some constructive criticism they are holding back?

This got me thinking. How do I respond to seeing Tableau Public workbooks?

The more I use Tableau Public, the higher and higher I believe the bar has to be set for a successful Tableau Public visualisation. You must think like a web designer when publishing to Tableau Public. Layout, fonts, interactivity, colour, etc: these consume vast tracts of web designers’ time for a reason. Just as a badly designed web page is a disastrous advert for your brand, so too is a weak Tableau Public viz. I’ll be exploring these issues in more detail in my session, “Expose yourself with Tableau Public”, at the Tableau Customer Conference in Las Vegas in October.

An anodyne retweet of my own

What is my own reaction to seeing Tableau Public visualisations? If I like it, I’ll comment on the blog, or tweet it. Good work deserves to be praised. What about my critical thoughts? Believe me, I see areas for improvement in almost all the visualisations I see; some recent popular Tableau Public vizzes by well known members of the Tableau community have been, in my opinion, really badly designed. Have I told them? No.

If I think your workbook needs redesigning or tweaking, generally, I say nothing. Why is that?

Because I appreciate effort – at least the author is using Tableau, and having a go. I wouldn’t want them to stop that. I think most authors just want to get their data out there. They aren’t interested in someone they probably don’t know dissing what might have taken them hours to create.

Because I question my own opinions: on whose authority am I an expert in Tableau Public? What if my opinions are wrong? I don’t get much criticism of my own work; I get almost universal praise. This is brilliant, but what if everyone else is also just hiding their critical thoughts about what I do? I think I’m pretty good at this Tableau-data-viz thing (actually, I’m quite confident I am good at it), but I don’t know for sure. Stephen Few is famous for his approach of calling things exactly as he sees them. If he has a problem with your work, he’ll share that with you and with the world, and justify those opinions. As a result he is widely read and widely respected. He has also stimulated many great debates as both his supporters and detractors explore the issues he raises.

Because I’m not sure I can express my opinions in a constructive manner. Stephen Few writes excellently, justifying his opinions. I am not sure I can critique well enough to cause the author to reflect rather than get angry.

Reading through the many thoughtful comments on Moose Peterson’s G+ post, I think I should rethink my approach.

What do you think? Would you be comfortable critiquing others’ Tableau Public workbooks? Would you behave differently on the internet as you do face-to-face? Would your freedom to critique others change when you become a Tableau employee (as I will be in 6 weeks)? How would you react if I started saying “nice viz, but your dashboard layout’s all wrong”?
