Suicides and Covid-19
Looking at the raw data behind two recent studies of early suicide counts during the Covid-19 pandemic gives me a chance to try out a “moving box plot” since the data is a bit sparse for regular confidence intervals.
Graphic Review: SPLC Hate Report
The Southern Policy Law Center has released its “The Year in Hate 2020” report (PDF) cataloguing hate group activity throughout the year. I review some of the graphs. Perhaps a closer look will raise our awareness of the content.
Welcome to Raw Data Studies
Welcome to my new blog of my visual explorations of data! Some say raw data doesn’t exist, so you can think of “raw” as applying to the studies rather than the data if that helps.
Until time is no more – bat charts
Can beauty exist without meaning? I examine a time-based stacked area chart where the time component is of dubious value. Plus a rare pie chart appearance and a quick scatterplot remake.
Economic convergence extrapolation
A suspicious regression chart from an economics working paper leads to an exploration that finds an error in the original and some interesting alternate views.
Scented candle ratings trends
It started with three questions about a chart. Diving into candle review ratings turns into a case for the “don’t smooth a smoother” rule.
Dog years, human years and DNA
A recent paper used DNA matching to support using a log function for dog-age to human-age conversions, but I’m not so sure the data supports it.
Bar-mekko water use chart

Insurance pricing oddity
A deeper dive into 93,000 insurance customer rate changes shared an analysis by The Markup. Making sense of suspicious residuals.
Relationship chord diagram study
I’ve never found chord diagrams very valuable, but I’m eager to learn where they are useful. Maybe I just need the right data.
