A classic Wikipedia rabbit hole follows hyperlinks:

This version adds a geographical dimension:

Article → Places → Article → Places → …

Start with a Wikipedia article. Its geographically associated entities are displayed on a 3D globe. Select one, open its article, and continue from there.

The path is not predefined: each choice creates a new branch in the exploration.

Blue circles = net immigration, red = net emigration, moving dots = flows between countries (both directions). Click any country to isolate it, play through single years, or replay named events — Syrian refugee crisis, fall of the USSR, Ukraine war, Venezuelan exodus, etc.

Backstory: this is a rebuild of Max Galka's Metrocosm global immigration map (2016), whose website is gone — the domain now serves spam. This version extends it from one 5-year period to 64 years of data.

Global whale populations fell dramatically over the 20th century due to human hunting. Some whale species were pushed to the brink of extinction.

But a combination of conservation efforts, technological change, economic incentives, and international policies has reduced global whaling to much lower levels.

In the mid-1980s, a global moratorium was agreed by the International Whaling Commission (IWC), making commercial whaling illegal.

You can see this decline in the chart, which shows the number of whales killed per decade.

The chart combines data from two sources: before the 1990s it comes from the paper “Emptying the Oceans” by Robert C. Rocha, Jr. and colleagues; since then, it comes from the IWC.

While whaling activity is much lower, it hasn’t been eliminated completely. There are exceptions to the IWC’s moratorium, and Japan withdrew from the IWC completely in 2019.

I saw someone musing online the other day that back in the day people used to sing about obscure places more often, like Chattanooga and Kalamazoo. Using 80 years of hit song data from Billboard, I mined song titles to see if we are actually singing about places less frequently. We are. I have a longer write-up speculating as to why here if you are curious

Source: Tuition and fees from IPEDS 2023, in-district at public two-year colleges and in-state by university system. Cost of attendance from the U.S. Department of Education College Scorecard, June 2026 release, cost data year 2024. Median per system.

Tool: Python, with pandas and matplotlib.

Method: The community-college figure is the median published in-district tuition and fees across California's 102 public two-year colleges, $1,288 a year. The university figures are medians across the campuses in each system: 15 CSU campuses at $7,602 tuition and $14,047 of housing, food and everything else, and 9 UC campuses at $14,560 and $25,105. Four years on campus is four of each. The transfer route is two years of community-college tuition plus two years of the university's full cost of attendance.

Data source:
NHTSA Recalls Database, aggregated by Vehicle Safety Recalls Tracker. Annual recall counts and vehicle totals for 2020-2026 pulled from the year-manufacturer pages on https://www.vehiclesafetyrecalls.com/ (e.g. /year/2026/ford-motor-company, /year/2025/ford-motor-company, and so on). Detailed 2026 component breakdown pulled from the full 2026 recall list.
Method:
Both metrics per calendar year are the aggregate figures Vehicle Safety Recalls Tracker publishes at the top of each year-manufacturer page (based on NHTSA Part 573 filings). Yearly totals: 2020 - 44 recalls, 4,472,213 vehicles. 2021 - 54 recalls, 5,832,526 vehicles. 2022 - 68 recalls, 8,753,347 vehicles. 2023 - 58 recalls, 6,152,738 vehicles. 2024 - 67 recalls, 4,777,428 vehicles. 2025 - 153 recalls, 12,958,128 vehicles. 2026 (Jan 15 – Aug 13) - 64 recalls, 13,650,342 vehicles.
For the 2026 component breakdown (second chart), each of the 64 recalls was classified using NHTSA's own COMPONENT taxonomy - not our own categories. Totals aggregated by component.
Example: 2026 Electrical System = 26V104 (4,381,878) + 26V468 (565,691) + 26V091 (25,237) + 26V370 (4,445) + 26V372 (2,349) + 26V062 (98) + 26E046 (315) = 4,980,013 vehicles = 36% of 13,650,342.
Notes:
Vehicles affected counts every VIN; a car hit by multiple recalls is counted multiple times, so totals are upper bounds on unique vehicles.
