TidyTuesday with Fable
A series of exploratory data analysis sessions on TidyTuesday datasets, produced by Jon Minton and Claude (Fable 5) — in two distinct working modes.
The sessions come in two kinds, and the site keeps them clearly separated because the way a page was made is part of what it is:
- Session 1 — co-developed. Built in a live, turn-by-turn conversation: Jon asks, Claude explores, they decide together what’s interesting and how to show it. Every Session 1 page carries a blue badge at the top.
- Session 2 — autonomously developed. Claude chose the datasets, the analytical angles, the visual designs and wrote the prose on its own, with no human steering during the session — checking its own figures in a browser as it went. Every Session 2 page carries a grey badge at the top.
There’s a short reflection on the two modes comparing how they felt and what came out differently.
Session 2 · autonomously developed
Fable’s own picks, analyses and designs — one page in each of four registers.
- How likely is ‘likely’? (statistical inference) (TidyTuesday 2026-03-10) — 5,174 people put numbers on 19 probability phrases. A Bradley–Terry model recovers a shared latent scale from pairwise choices alone, the public is tested against the UK intelligence “yardstick,” and a within-person coherence curve turns words into a psychophysics experiment.
- Thirteen males per female: an island running out of mothers (substantive demography) (TidyTuesday 2026-03-03) — sixteen years of capture data on the Hermann’s tortoises of Golem Grad, where sexual harassment, emaciation and tiny clutches compound into a projected extinction. The mechanism of a “demographic suicide,” measurement by measurement.
- A million digits of π, and not a pattern in sight (novel visuals + randomness theory) (TidyTuesday 2026-03-24) — a turtle walk through 100,000 digits, a convergence funnel, a digit-pair heatmap and the Feynman point: every test for pattern comes back empty, on a number that is the opposite of random.
- How a cold sea breathes (physical time series) (TidyTuesday 2026-03-31) — eight years of a Nova Scotia water column as a depth–time heatmap: the annual heat pulse damping and lagging as it sinks, and the winter weeks when the sea turns upside-down.
Session 1 · co-developed
Built live, in conversation — the original sessions.
- Who gets to stay home? European parenting leave, 1970–2024 (TidyTuesday 2026-06-02) — the arrival of co-parent leave, definitional traps in harmonised policy data, and what 55 years of leave policy do (and don’t) say about the fertility decline debate.
- Is the video game movie curse lifting? (TidyTuesday 2026-06-09) — a 15-minute sprint: the ¥5bn Pokémon box-office trap, three decades of rotten reviews turning a corner in 2019, and why opening-night audiences grade these films a letter or three above the critics.
- A garden of glyphs: edible plants as flowers (TidyTuesday 2026-02-03) — Chernoff faces, reimagined as flowers: each crop’s growing requirements rendered as petals, centre and colour, iris-dataset style.
- The world, sister by sister (TidyTuesday 2026-05-12) — an interactive Leaflet map of 10,596 sister-city links: hover to fan out a city’s twins, click to pin and compare.
- The frontier of human longevity, on a Lexis plane (TidyTuesday 2023-05-30) — the 200 oldest verified people as lifelines on a Lexis diagram, the stagnating longevity record, and the Calment anomaly.
- Birth is scheduled: calendar effects in US births (TidyTuesday 2018-10-02) — the working-week birth, holiday troughs, and the measurable 5.3% dip on Friday the 13th.
