I'm the creator of subway.fyi, that uses historical data to forecast outages (sometimes 30 minutes ahead of the MTA), and allows replays of every incident in the system.

I keep hearing about the 15-minute city, and I wanted to see how far you could get in the city in 15, 30, or 60 minutes during a morning rush hour. This was the result!

1. Times Square.
2. Coney Island
3. Jamaica

Feedback welcome of course.

Tools: Python, NumPy, SciPy, Matplotlib, TimescaleDB. Data: MTA GTFS-Realtime, captured myself. More data at subway.fyi.

Source: Kola Superdeep Borehole depth from Popov et al. (1999). Earth radius and internal layers from NASA and USGS. Eiffel Tower height: 330 metres.

Tools: Python with Pillow. The Earth cross-section uses an exact radial scale.

At full 5400 px resolution, the true scale borehole depth is 3.46 px.

The borehole is approximately 37 Eiffel Towers deep. If Earth were reduced to 1 metre wide, the hole would be 0.96 mm deep.

A month-by-month map of territorial changes during Germany’s campaigns from the invasion of Poland to the aftermath of the fall of France. The map represents land control rather than aerial or naval operations.

This map shows the incorporated places in the lower 48 states and a gradient showing the distance from these incorporated places, the furthest place from any incorporated community is 38.598639, -116.901556 in Nevada. Which funnily enough is near a ghost town named Belmont.

I have always been fascinated by history and dynasties. This is what prompted me to build this interactive dataviz (with the help of AI - I could not code that alone).

It is a world family tree of all major ruling dynasties, from Ancient Egypt to the current day.

Presented in three views:

• Bloodlines: vertical position is birth year. Horizontal position starts in the person's nation but moves towards their relatives. The columns blur together as houses merge.
• Nations: Same time scale, but every nation is pinned into its own column and packed locally. A line leaving a column is a marriage or a birth that crossed a border.
• Ties: In this view, time is removed. Each nation is represented as a circle. The circles are spread out by a spring model where the pull between any two is the number of people whose parent, child or spouse sat in the other one. Nations that intermarried end up touching.

476 cities were scraped from Numbeo's cost of living calculator in July 2026. Each bar is one city's McDonald's combo meal (or fast food equivalent) price divided by its average monthly net salary after tax. Numbeo's data is crowd sourced and may be inaccurate.

This maps the demographic profile of countries around the world in ten-year snapshots from 1953 to 2023: a population pyramid by age and sex, a mortality distribution, and a fertility profile (PASFR).

Turkey uses a centralized university admissions system. Students take the nationwide YKS exam, receive a score and ranking, submit a preference list, and are placed into programs centrally. This chart shows which majors appear among the most selective undergraduate programs in the quantitative track over time.

I like maps because they turn lists of dates into spatial relationships. Timelapses take that one step further: compress three centuries into seconds, and a seemingly static map begins to feel alive.

I made this from historical data compiled for the map of my solo-developed game. It shows 147 conventional city-founding dates and ten historic route corridors. Political borders are omitted because no single boundary layer would be accurate across the entire period. The dates do not represent first human settlement, and the routes are not a complete history of colonization and migration.

The map belongs to Salt and Soil, a colony sim about one family living through a changing American frontier. Its public Steam Playtest is open through August 19.
