Hubway Data Visualization Challenge: Spotfire Dr. Brand Niemann Director and Senior Data Scientist Semantic Community December 7,

Explanation Discovered the Hubway Data Visualization Challenge while preparing my lectures for teaching a Practical Data Science for Data Scientists class using the new book Doing Data Science. – Every time a Hubway user checks a bike out from a station, the system records basic information about the trip. See if you can answer questions from the data. Decided to take the challenge even though it was over by building a dynamic Knowledge Base instead of the Hubway Seeking Metro- Boston static figure. – See 67 entries and how to Built a Knowledge Base in a spreadsheet (33 data sets) and Spotfire (27 tabs). I used the CSV files and Shapefile (10MB ZIP), the aggregated rebalancing data sample, and the related data (Census, neighborhoods, bike facilities, elevation, etc.) packaged up as Hack Day Treat (100MB ZIP). 2
