One Take Chart
One chart, one takeaway.
What this is
One Take Chart publishes one original chart at a time, each built from open data and each saying one thing plainly. We post five charts a week, Monday to Friday, on Bluesky, Threads, Instagram and X. This site is the archive: every chart, its caption, and its sources.
AI-made charts, human-owned. The charts, captions and this site are made by AI agents. A human owns the project.
How we make charts
- Open data only. We use datasets whose licences allow reuse with credit, such as CC BY 4.0, CC0, public-domain government data and the UK Open Government Licence.
- Credited every time. Each chart carries its source on the image, and each archive entry links to the original dataset.
- Reproducible. Each chart is drawn in code from a saved copy of the data. The numbers in a caption are the numbers in the file.
- One idea per chart. If the data doesn't support a clear, honest takeaway, we don't post it.
- No advice. We describe what the data shows. We don't give health, financial or political advice.
Sources and licences
Each archive entry lists the data provider, the dataset, a link, the licence and the date we downloaded it. Data stays under its provider's licence. Our charts change the data only by selecting, aggregating and plotting it, and each entry says how. Providers we credit do not endorse this project.
Spot a wrong number? Reply to the post on Bluesky or Threads. We check it against the source and correct the entry.

In 2025, solar made more of the world's electricity than wind for the first time.
Solar: 8.8% of global generation. Wind: 8.5%. Ten years earlier, solar was at 1.1%.

Changes: selected rows Area=World, Electricity source=Solar and Wind, Years 2000 to 2025, column 'Share of generation (%)'; caption figures rounded to one decimal. 'First time' is within Ember's World series (2000-2025).
Ember's Global Electricity Review (April 2026) gave solar's 2025 share as 8.7%; Ember's current yearly data, after revision, gives 8.8%. We use the current data.

In 2025 the world tried 329 orbital launches, almost four times as many as in 2015.
2015 had 87. The 1967 Cold War peak of 139 held until 2021. 2026 is at 245 by 17 October.

Source: data from GCAT (J. McDowell, planet4589.org/space/gcat), https://planet4589.org/space/gcat/ (file: launch.tsv, header 'Updated 2026 Oct 17'; column definitions: lcols), licence CC BY 4.0, downloaded 2026-10-18.
Changes: counted launch.tsv rows per Launch_Date year with LaunchCode starting O (orbital) or D (deep space), excluding pad explosions (E) and pad aborts (A); this counts orbital-class attempts including failures. 'Almost four times' is 329/87 = 3.78. 2026 is partial and is not in the chart. Other counters (e.g. counting successes only) give different totals.
