Nested Bar Charts by Allen Yee
When it comes to data visualization, I’ve always been a bit curious why there wasn’t a nested bar chart interface where one could explore the figures/information that make up a specific piece of data. And how can it also be done in an engaging and interactive way?
I used 2010 census data about New York City’s population by borough and neighborhood, available on NYC Open Data. With this visualization, you can visually see the population of each neighborhood and how many people and all the neighborhoods that make up the millions of people who live in the five boroughs of New York City. Taking a different data set, I gathered data about all cars sold in the US in 2018 and visualized it as well.
This visualization is also a continuation of another design investigation I made a few years prior: NYC Trees. It’s safe to say that I like bar charts. I love its simplicity and the exploration of possibilities when it comes to this well-known method of graphing.
