Visualize the Philadelphia School District‘s budget with a tool built by local civic hackers Chris Alfano and Lauren Ancona.

The pair built the visualization, which shows the District’s 2014 budget and proposed 2015 budget, at this month’s EdTech Hackathon with budget data the District released ahead of the event. District representatives said they hoped technologists would use the data to build tools that could increase transparency by making the budget easier to understand.
