My blog post earlier today, "In defence of data visualization rules" sparked some interesting discussion online. Ben Jones wrote a very thoughtful comment but most of the back-and-forth was on Twitter. I thought some of the points made there were interesting, including some valid criticism, so I've tried to summarize the highlights in the Storify below.
Based on the feedback from Alberto Cairo and Ben Jones specifically, I've also updated my original post to clarify that the rule that the y-axis should start at zero generally applies to bar charts and not necessarily to other chart types.
I don't argree with role #1. Pie charts are not so bad to visualization. They're one of the best way to explain some general data and they are easy to understand, I'm using this pie charts http://www.pptstar.com/diagrams/timeline-calendar-diagram/. But for more specific information it's better use other ways. I all depends.
