theodp writes: As part of its ‘Iron Viz’ data visualization contests that lead up to its annual conferences, Tableau Software ($4.8B market cap) has awarded $500 gift cards to ‘Twitter Crowd Favorites’, contestants whose data viz draw the most ‘votes’ (tagged Tweets) on Twitter. But no more. As it expanded Iron Viz eligibility to China, Tableau said it ‘just didn’t seem fair’ to allow popular voting in its worldwide contests since the Chinese government blocks citizens’ Twitter use. “As Chinese authors join the contest,” the Tableau Public blog explained, “we have to say goodbye to the Twitter Crowd Favorite. Twitter is blocked in mainland China and it wouldn’t be fair for our Chinese contestants.” And the latest Iron Viz Contest FAQs confirm the change: “Q. I heard there won’t be a Crowd Favorite prize, is that true? A. Absolutely true. China is among the new countries who can take part in the Iron Viz, and Twitter doesn’t work in mainland China. The usual Twitter Popular Vote just didn’t seem fair.”
This XKCD comic still has my all-time favorite data visualizations.
