This is a really incredible data visualization about human population all over the world. It used some simple green histogram to show the population density.
This picture does not look complex, but this is a really easy-looking and understandable picture to show. In addition, you can zoom the picture very very much, like Manhattan in New York City, I will show it in the following pictures.
What’s more, we can also find something from the change of 1990-2015. For example, you can see the population in Chicago is decreasing, but in New york is increasing.
In general, this is an amazing and marvellous graph.
