Why do people mention which slop bot made something for them? Brand loyalty? Why not say nothing and let people think you used your own knowledge and abilities?

What is with all the "πŸ“Š for kids" books lately?

Is it just slop bots driving the cost of illustration to zero?

Do parents really buy these to read to their kids? Is it a rΓ©sumΓ© padding exercise for the authors?

The StatsCan website is baffling.

Every dataviz product is meticulously documented with authorship, update cadence, underlying datasets, keywords, related outputs... everything but a link to the actual viz! πŸ“Š

Once you know to look out for conditioning on the outcome, you see it sneaking up on you around every corner!

I wonder whether the categorization of farmers into "large" and "small" in the data used for this visualization πŸ“Š of income inequality in 19th c. France amounts to conditioning on the outcome. Or maybe it's by acreage?

I'm guessing this is with the water already at a full boil, which is never how I cook pasta.

Those born in 1919 were the right age to die in WWII, or is that already accounted for here?

A chart with overlapped bars.

A chart with overlapped bars.

Am I wrong to think that overlapping bars is just straightforwardly an error? Now area (and thus visual impact) is no longer proportional to the data. Maybe I'm too VDQI-pilled? #dataviz πŸ“Š

Well, @newyorker.com... is this "re-signed" or "resigned"? Why leave this at a line break? You'll use the dieresis but not the double hyphen?

The first portrait of Gutenberg appeared 99 years after his death, so the likeness here is, unfortunately, just a guess at what he might have looked like.

"Electrons" seems like a strange way to describe a category of energy sources. Wood and coal contain electrons!

Chapter 6 of Casella & Berger is a real page-turner!

It's a bit funny to read them introduce the likelihood principle and credible intervals while carefully avoiding the term "Bayesian".

At first I thought I'd like this better with filled, triangular arrowheads, but upon further reflection I think this style makes it more obvious where the data points are.

Is there an unconscious tendency to imagine the data point in the centre of a filled arrowhead instead of at the tip?

Can you guess which basic #dataviz errors this graphic features?

Why in the world wouldn't the colour mapping be the same across the four donuts?

And why not a 100% stacked bar chart instead of donuts?

Just like movies about making movies, data graphics about making data graphics are never good.

If you're looking for more on this sort of thing, what we did here was "enumerate non-decreasing sequences".

A lot of these elementary enumeration problems hinge on recursion: a non-decreasing sequence of length n+m is comprised of one of length m glued to the end of one of length n.
