Shrinking a Chart Changes What It Says

Shrinking a Chart Changes What It Says

Responsive design arrived in data visualization as a layout problem. Squeeze the axes, rotate the labels, drop a legend, ship it. The chart got smaller, the content stayed the same, and the job was a media query.

The Science of When to Animate a Chart

The Science of When to Animate a Chart

There are two confident positions on animated charts and both are wrong. One says animation is decoration, a gimmick for people who cannot make a point with a static image. The other treats motion as self-evidently engaging and reaches for it by default. Neither camp seems to have read the research, which is unusual in being specific enough to settle the argument, and specific enough to embarrass both sides.

How to Show Uncertainty Without Losing the Reader

Here is a question with a number attached. You are in Midtown Manhattan and you need to be on the Upper East Side. How long does the taxi take? I have the answer, from 8,762 real trips between those two zones in January 2024. The average is 13.2 minutes. If I follow the convention of my field and put an error bar on that average, using the 95% confidence interval the way thousands of published charts do, here is what I am telling you.

There Are Only Four Ways to Tell a Data Story

There Are Only Four Ways to Tell a Data Story

Most advice about data storytelling is atmospheric. Find the narrative. Take the reader on a journey. Make it flow. None of it tells you what to actually build on Monday, which is why the same three failures keep shipping: the chart post that dumps a filterable table on a reader who wanted a sentence, the dashboard nobody can summarise, and the expensive interactive that everybody praised and nobody used.

Your Scatterplot Is Hiding Half Its Data

Your Scatterplot Is Hiding Half Its Data

Below is a scatterplot of New York City yellow taxi trips from January 2024, fare against distance. It is real data, straight from the city's own records. I cropped the axes to trips of 0 to 20 miles and 0 to 90 dollars, which holds 2,836,835 of the month's 2,964,624 records, or 95.7 percent of them, and keeps the file's nonsense out of the frame: one trip is logged at 312,722 miles, another at minus 899 dollars. Inside that window, nothing has been done to the data but draw a dot for each trip.

Twelve Lines Is Not a Chart, It's a Warning

Twelve Lines Is Not a Chart, It's a Warning

This is the most common way a real chart fails, and it has nothing to do with the famous sins of deception. Nobody truncated an axis or inverted a scale here. The data is honest. The chart is simply overloaded, and overload is its own kind of lie: it presents information while quietly making that information impossible to read.

People Remember Your Title, Not Your Chart

People Remember Your Title, Not Your Chart

Most people who share a news story never open it. When researchers matched 2.8 million shared links against the clicks they actually generated, 59 percent of the links were never clicked at all. A separate study of 35 million Facebook posts found that about three quarters of news-link shares were made without the sharer opening the article first. The headline did the work. The article was scenery.

The Canada Tariff That Spared Your Gas Tank

On 21 July the United States announced a 50 percent tariff on Canada, and the coverage split into two familiar camps almost instantly: this is a bold stand against an unfair trading partner, or this is a reckless tax on American consumers. Both camps mostly skipped the part that actually tells you what the tariff is for. Read the exemptions.

The Excel Error That Ran the World

In early 2013 a third-year economics PhD student at the University of Massachusetts Amherst was given a routine assignment: take a famous empirical paper and try to reproduce it. Thomas Herndon, then 28, picked the most influential macroeconomics paper of the decade. He could not make the numbers come out. He emailed the authors, and to their considerable credit they sent him their original working spreadsheet.

The Richest Country in Europe Is an Accounting Trick

Pull up almost any ranking of the world's richest countries and Ireland is sitting at or near the top, a small island out-earning Switzerland, Norway, and the United States per head. It is the kind of stat that goes viral: little Ireland, richest in Europe. There is only one problem.

The 911,000 Jobs That Never Existed

On the first Friday of most months, at 8:30 a.m. Eastern, a single number moves trillions of dollars. Traders position for it, the Federal Reserve leans on it, campaigns cut ads around it, and the wire services race to publish it within seconds. The number is the monthly change in nonfarm payrolls.

The Misleading Chart Tricks That Fool You Most, Ranked

The Misleading Chart Tricks That Fool You Most, Ranked

In 1954 a journalist named Darrell Huff published a slim book that taught a generation how to lie with a graph. How to Lie with Statistics gave the tricks names. The Gee-Whiz Graph chops off its own baseline so a rounding error looks like a boom. The One-Dimensional Picture draws a doubled number as a blob with four times the area. Seventy years later the tricks have not changed. What changed, in January 2026, is that a machine learned to draw them by the thousand.
