Interactive Map: What people know about the world's cities

Hi sub,

I am the creator of a **Square Mile**, a geography game where players are asked to recognise streets, metro and bus stations, bridges, and landmarks on blank city maps.

After more than 12,000 rounds played, and more than 240,000 items asked and answered (or not), I created **Mind Map**, a data visualisation that summarises what people know about the world cities.

You can explore the interactive map here: [https://www.habibicode.org/mindmap](https://www.habibicode.org/mindmap) and play a few rounds on your city. The game is free, require no sign up, stores no data besides your answers, and currently is available for 130+ cities.

The dataviz has 3 views:

* **Streets:** this view shows how well people recognise the street when asked about it. Clicking on a street opens a chart showing you the %age of people that recognise each portion of the street (the game crops the city map, so streets are often asked in segments) * **Metro**: this view shows how well people identify different metro stations. Clicking on a station or line opens a detailed view of it. * **Landmarks:** shows how well people recognise famous landmarks in the cities.

You can also play with the views on each city:

* **Angle:** a 3D view of the data where depth = %age answered * **Side:** a horizontal bar charts that provides an idea of the average answer %age in a city

And a few more options

Hope you enjoy it!
