About this app
My coworker John Nelson has created a very interesting story map - Taxi Cab Terrain,
looking at Yellow Cab trip data in New York City from July 2015 - June 2016.
By mapping the data John has been able to pick out how different New York boroughs use and pay for taxi cab journeys.
He then looks at the underlying socio-economic data in those neighborhoods to see if they help explain the differences
in how inhabitants of different New York neighborhoods use and pay for cabs.
I helped John on this project to process and aggregate the data that he used to create the story map,
which was massive - there are more than 10 millions yellow cab ride in NYC each month, and we have over 130 millions records in total for the entire year...
I was able to handle these data using PostgreSQL database, and I thought it would also be nice to visualize these data dynamically,
therefore, I put together this app, the data are queried and aggregated in the back end using Node.js and in the front end,
these data are rendered into thousands of hexagons with different sizes using Canvas Layer inspired by this map
