Fantastic write-up about data visualization issues such as clarity, accessibility, using descriptive text, and more with great examples from @ourworldindata.org by Saloni (@scientificdiscovery.dev). Great place to start for data visualization enthusiasts and students. 👏

Teaching data visualization? Our research reveals that students need more support with procedural knowledge (tracing polylines, mapping colors to polylines) when learning Parallel Coordinates Plots. The Anderson & Krathwohl taxonomy helped us pinpoint exactly where interventions should focus.

Graph with title: Older people are addicted to their digital gadgets. But the graph itself only has data about device ownership %

Graph with title: Older people are addicted to their digital gadgets. But the graph itself only has data about device ownership %

This graph that the @economist.com is boosting on Facebook is irresponsible.

Titles create powerful frames in the way people interpret data (see: Kong et al 2019, www.hidykong.com/papers/Kong-...). This one tells a story that doesn't exist in the charted data.

AI is not a mere tool for helping teachers. When you remove the human element of teaching and learning, you are not being more efficient nor effective. The ability to learn is what makes us human, and humans teaching humans is a fundamentally human act that is necessary for meaningful engagement.

What Americans die from and the causes of death the US media reports on.

4 stacked bar charts. showing in short that while heart diseases and cancer constitutes 55% of the causes of death, they receive about 7% of the media coverages. Homicide is under 1% but receives between 42% and 52%. Terrorisme barely registers in the causes of death, but gets between 11% and 18%.

The first stacked bar is causes of death in the US in 2023
Heart diseases 29%
Cancer 26%
Accidents 9.5%
Stroke 6.9%
Lower respiratory diseases (6.2%)
Alzheimer's disease (4.8%)

Note: Based on the share of causes of death in the US and the share of mentions for each of the causes in the New York Times, the Washington Post and Fox News. All values are normalized to 100%, so the shares are relative to all deaths caused by the 12 most common causes + drug overdoses, homicides and terrorism. These causes account for more than 75% of deaths in the US.
A "media mention" is a published article in one of the outlets which mentions the cause (e.g. "influenza) or related keywords (e.g. "flu") least twice.

This is why I get annoyed when people say AI will help identify struggling college students. In every big lecture I teach, at least one or two students fail because they never show up or turn in any work—despite weekly emails from me and TAs. We don’t need AI. We need more humans to support them.
