A son of friends, we’ll call him Avery, was tasked with every 4th grader’s nightmare – prepare and deliver a presentation on one of the US states. When I was in 4th grade, we didn’t have PowerPoint or wikipedia. I think I made a poster that includes pictures clipped from…
We don’t just report the facts, ma’am. We use a set of values to make judgments about the data, like which of these results is good or needs improvement, etc. We set benchmarks and cut points so our clients can understand when action needs to be taken and where. Yet…
When it comes to qualitative data, we have far fewer dataviz tools at our disposal. Another time, promise, we’ll get into word clouds and what Stuart Henderson thinks of them. Today, let’s tackle a more common method of displaying qualitative data – quotes. In reports, quotes are usually shown…

Wow, the action in the dataviz/tech world this past week has been awesome! A female programmer at a Python (that’s a programming language also used for dataviz) conference was fired after tweeting about the sexist jokes she was hearing from a largely white young male crowd, and Tableau’s…
