Best of the visualization web
At the end of each month I pull together a collection of links to some of the most relevant, interesting or thought-provoking web content I've come across during the previous month. Here's the latest collection from January 2018. Visualisations & Infographics Includes static and interactive visualisation examples, infographics and galleries/collections of relevant imagery. SRF | 'Roger Federer: 20 Years, 20 Titles' Mapping Police Violence | '2017 Police Violence Report... collected data on over 1,100 killings by police in 2017.' SCMP | '2017: the safest skies record' SCMP | ... and here's a photo of the print version Economics | 'All the president’s tweets' Pixel Mixer | 'Anatomy of a Viz - The Level is in the Details' Mike Vizneros | 'A Chamber Divided: What We Can Learn By Using BioFabric Charts' Taylor Baldwin | 'Audiofabric' Guardian | 'Bussed out: How America moves its homeless' Twitter | 'A climate change cross stitch' Guardian | 'How the NHS winter beds crisis is hitting patient care'

10 Christ-like Figures Who Pre-Date Jesus
Religion I recently watched the documentary Zeitgeist (Part 1) as well as Bill Maher’s movie Religulous. Both made mention of claims often made that there are many stories that predate Jesus but have striking parallels. I decided to follow up on these claims and see what kind of information was out there to substantiate these assertions. I found several websites run by Christians who obviously disputed all claims of any parallels to the life of Jesus. I also found several interesting books on the subject, such as The World’s Sixteen Crucified Saviors: Christianity Before Christ by Kersey Graves, and The Christ Conspiracy, and Suns of God: Krishna, Buddha and Christ Unveiled by Acharya S. As a non-christian, I am approaching this topic purely as an interested observer. Here are ten of the figures often sited: Both went to their temples at the age of twelve, where they are said to have astonished all with their wisdom. Jesus responded: “…begone, Satan!” Heracles is the Son of a god (Zeus).
Numbers Rule Your World
Two years ago, Wired breathlessly extolled the virtues of A/B testing (link). A lot of Web companies are in the forefront of running hundreds or thousands of tests daily. The reality is that most A/B tests fail. A/B tests fail for many reasons. Bad outcome isn't the primary reason for A/B test failure. 1. 2. 3. These issues are often ignored or dismissed. The Facebook Data Science team just launched an open platform for running online experiments, called PlanOut. The rest of this post gets into some technical, sausage-factory stuff, so be warned. Bad design is when the experiment is set up in such a way that it does not provide data to answer the research question. Let's say you want to test changing the text on your registration button from "Sign up Now" to "Join Free". The problem is noise in your data. The examples of failed designs are endless. Worse than bad or no design is bad execution of a good design. Start with the experimental unit. - integrated logging - quality-control charts

40 Essential Tools and Resources to Visualize Data
One of the most frequent questions I get is, "What software do you use to visualize data?" A lot of people are excited to play with their data, but don't know how to go about doing it or even start. Here are the tools I use or have used and resources that I own or found helpful for data visualization – starting with organizing the data, to graphs and charts, and lastly, animation and interaction. Organizing the Data by sleepy sparrow Data are hardly ever in the format that you need them to be in. PHP was the first scripting language I learned that was well-suited for the Web, so I'm pretty comfortable with it. Python Most computer science types - at least the ones I've worked with - scoff at PHP and opt for Python mostly because Python code is often better structured (as a requirement) and has cooler server-side functions. MySQL When I have a lot of data - like on the magnitude of the tends to hundreds of thousands - I use PHP or Python to stick it in a MySQL database. Ah, good old R.
Visual Business Intelligence
We typically think of quantitative scales as linear, with equal quantities from one labeled value to the next. For example, a quantitative scale ranging from 0 to 1000 might be subdivided into equal intervals of 100 each. Linear scales seem natural to us. If we took a car trip of 1000 miles, we might imagine that distance as subdivided into ten 100 mile segments. It isn’t likely that we would imagine it subdivided into four logarithmic segments consisting of 1, 9, 90, and 900 mile intervals. Logarithms and their scales are quite useful in mathematics and at times in data analysis, but they are only useful for presenting data on those relatively rare cases when addressing an audience that consists of those who have been trained to think in logarithms. For my own analytical purposes, I use logarithmic scales primarily for a single task: to compare rates of change. I decided to write this blog piece when I ran across the following graph in Steven Pinker’s new book Enlightenment Now:
