Newsrooms have been publishing maps for a long time. However, mapping on the web is very difficult due to the sheer amount of data involved. Some of the largest datasets available to journalists are geospatial. The U.S. TIGER/Line roads database, for example, tips the scale at 9.2 gigabytes, and the USGS’s national hydrography data set is 17 gigabytes compressed.
The data needed to analyze legislative redistricting is similarly huge. In California alone there are 700,000 Census blocks. When we started covering redistricting last year, we knew we would need an easy way to present vast amounts data quickly. We took a serious look at both Mapnik and Mapserver — who are still leaders in the field — but the Ruby bindings support in both, at the time, weren’t as robust and stable as we needed them to be.
Once again, we’ve taken all the data used on the government’s stimulus Web site, Recovery.gov, spiffed it up and added thousands of other recovery spending records — the law doesn’t require all recipients to report to Recovery.gov.
The Komen foundation’s decision to cut funding to Planned Parenthood set off such an uproar that the charity quickly gave it back. We trace how their explanations changed along the way.
Fracking has only recently become a household word, but government involvement with the drilling technique goes back decades. We trace officials’ moves—and levels of caution—over time.
What and where are the super PACs spending?
Today we published a small graphic, “Anatomy of a Trade,” to accompany an article about Freddie Mac by ProPublica’s Jesse Eisinger and NPR News’s Chris Arnold. The article describes some “financial alchemy” performed by Freddie to protect one of their mortgage-backed investments. The stakes were high and the financial details enormously complex, so we wanted to walk readers through things step-by-step.
We wrote a small framework to handle the transitioning logic which is over on GitHub. At their base, stepper graphics are just slideshows, and slideshows are just linked lists, so our library simply uses a linked list to control navigation.
Well-funded interests on either side of SOPA and PIPA are lining up support among members of Congress. This database keeps track of where members of Congress stand.
The ProPublica News Apps desk is looking for a smart, technically-savvy journalist to join our team for a pilot project we’re calling a News Applications Fellowship.
In this special internship, which is paid and will run until the end of the year, you’ll help us test a hypothesis: Can a smart, technical journalist with excellent and proven skills in other nerdy newsroom disciplines like graphics and CAR become a news app developer?
Democrats recognized that they could protect Jerry McNerney from being redistricted out of office by the Citizen’s Redistricting Commission.
If you’re trying to make your fixed-width site adaptive, there are some things you need to know about the
We’re debuting a new feature today as part of Marshall Allen’s story about one woman’s fight with a Texas hospital to find out how her husband died.
In the course of reporting the piece, Marshall made over 500 annotations in 64 documents he uploaded to DocumentCloud, many of which were sources of facts in his story. He told us about this wealth of metadata, and wanted a way to present it to readers. We agreed that we didn’t want to show them in a separate graphic or interactive feature, but rather sprinkled throughout the story itself.
So we made a special feature we’re calling Explore Sources. To try it, click the “ON” button next to “Explore Sources” at the beginning of the article. Words and phrases throughout the piece will turn yellow. Click these yellow highlights to see the portion of the source document from which Marshall got that fact. Once the annotation is visible, click the document image inside of the popup to go to the full document in DocumentCloud, or anywhere else to dismiss it.
Today we're launching a new look for people reading ProPublica on smartphones.
In order to make our site more welcoming for the increasing number of you who read us on your smartphones, we've redesigned and re-engineered the site so that people on small screens will automatically see a version of the site optimized to fit them. If you're on a smartphone, you've already seen the new look.
You don’t need any app or special URL to see it. Just go to www.propublica.org. If you’re on your phone, you'll see our optimized site. Readers of our website using desktop browsers shouldn't notice a difference.
Today we’re launching a new feature that lets readers work alongside ProPublica reporters — and each other — to identify key bits of information in documents, and to share what they’ve found. We call it DocDiver.
Fair Districts Mass says it is an independent group seeking better representation for minorities, but it has proposed maps that call its motives into question.
Congresswoman Corrine Brown, an African-American Democrat from Florida, represents one of the most irregularly shaped districts in the nation.

Use this database to find campaign contributions from some ALEC-affiliated groups to some ALEC-member state legislators.
Last week we published The Opportunity Gap, a news application that lets readers find out how equally their state provides poor and wealthier schools access to advanced classes that researchers say will help students later in life.
We designed the app so it was oriented behaviorally, and not just hierarchically. That is, rather than simply showing users a collection of items (as so many interactive databases do), we wanted to encourage people to take the conversations they were already having about their schools and communities, and extend that behavior onto our app. We owe a debt to Nick Disabato, whose SXSW panel got us thinking about this concept. We were also inspired by The New York Times’ Oscars app, which uses Facebook to let readers create, share and compare their ballots with friends, and to let them reproduce real-world behavior — competing on Oscar predictions — within a news app.
This emphasis on encouraging behavior — coupled with our preference for keeping our apps light on database writes — spurred us to integrate Facebook in a deeper way than we’ve done before.
