Public School Accessibility
How long does it take to walk or take public transit to the nearest public school throughout the city? How has that changed, city-wide, after the recent public school closings?
Let's build an interactive map that visualizes travel time to the closest public school — with options to show the map with the data from before the closing, after the closing, or allow the user to build their own map by interactively closing or opening existing schools.
