If you wander around any particularly large city, especially in winter, you’ll notice how little sunlight actually reaches the streets. In this visualisation (and accompanying story), The New York Times explore how the shadows of New York City change over the year. What’s really cool is that you can interact with the visualisation to find out how long a particular part of the city is in shadow over the day in each season.
