Behind the Scenes Look at mbtaviz

It's time for us all to meet up! We've been on quite the hiatus, but I am thrilled to kick things back into gear with an incredible talk. Big thanks to the MIT Media Lab for hosting us!


Visualizing MBTA Data is an interactive report of the performance and behavior of Boston's subway system that we launched in June. This talk will outline how we combined traditional and modern visualization techniques to create this application. We'll cover the design process, lessons learned from collecting and processing train data, how we built and scaled a large D3.js based project with a responsive UI, and techniques for exploratory visualizations.  We’ll also touch on what’s happened with the project since the launch including the release of the website source code and feedback we’ve received from the MBTA and other groups.

Author Bios:

Mike Barry is a software engineer at Twitter who focuses on backend services and data analysis, Brian Card is a software engineer at ViaSat who focuses on UI design and network management. Both Mike and Brian have an active interest in data visualization and analysis. This project was expanded from a graduate course on data visualization from WPI where Mike and Brian are part time students.

This meetup is kindly sponsored by Bocoup, where we're working to move data visualization forward on the open web. There will be some food and beverages.

    the presentation of Work was very good, particularly the way those guys showed up the difficulties and solution they found to overcome that, was very informative
