Interactive Big Data Exploration and VisualizationThe NYC taxi dataset contains over 1 billion taxi trips in New York City between January 2009 and December 2017 and is provided by the NYC Taxi and LimousineCommision (TLC)[1]. It contains not only information about the regular yellow cabs, but also green taxis, which started in August 2013, and For-Hire Vehicle (e.gUber) starting from January 2015. In the data, each taxi trip is recorded with information such as the pickup and dropoff locations, datetime, number of passengers,trip distance, fare amount, tip amount, etc. This workflow showcases the combination of using Spark to analyse huge amount of data, while still making the process interactive via the Webportal.
