Anthropic's spiderweb chart on AI task coverage is a case study in how radar charts obscure comparisons that a simple bar chart would make immediately clear.

LinkedIn: Most Radar Charts Should Just Be Bar Charts

A universal truth: most radar charts should just be bar charts.

The most recent Anthropic paper on the economic impact of AI had a standout data viz - this spiderweb radar chart showing their estimation of the reach of AI into various job tasks.

Blue represents the theoretical AI coverage of a set of tasks while red is a bit of a guess (from Anthropic's own usage data) about actual coverage today.

I get it, the radar view is alluring and kinda spooky, etc. But per usual, this probably should have been a bar chart.

So I re-charted 😁

Easy to compare across the categories and the ranking of occupations is frankly just calming to my mind.

...even though the data is kinda alarming.
