I've spent the quarter compiling and analyzing data exploring the persistence of Chicago art galleries, as a way of exploring CAR for the arts. I found a list from the Chicago Artists' Coalition of 96 such businesses that existed in 1990, and tracked their fate. A story summarizing the trend follows (an assignment for my Arts Reporting class) Read More...
It's been a busy week for the programming journalists -- as I'm sure you've seen. Congrats to all, especially the dev team at The New York Times, who just released the newest version of the Congress API, with plenty more robust features to play with, as well as my recent Data Delver interviewee Andy Boyle (who is #11 in my backlog, I'll get to you all before NICAR, I promise!) who just released a Django app, with the help of his St Read More...
This week I tackled recreating Ben Fry's Zipdecode project, which he gives great step-by-step instructions for in his Visualizing Data book that I have been following along with this quarter. It's an interesting take on the concept of the scatterplot, even before using its interactive features, it asserts its usefulness as a population density map Read More...
Information is fascinating at many different levels. Show me a simple graph of the components that make up a whole, that tells me something. I've found almost anything is more interesting when looked at across time, since it adds another dimension. This also helps with analysis, because outliers or rapid changes are often related to historical events Read More...
I'm not anything resembling a visual genius, but I like to believe I have enough of an eye that I can tell what works and what doesn't. The reason Tufte's books are so helpful is that they tell me why something works, and give me rules so I know what I can and can't do. That's why I have great appreciation for the Tufte chapter of the week: "The Smallest Effective Difference" in my ongoing exploration of "Visual Explanations Read More...
At Medill, there's a wonderful tradition called the "Medill F." Make a factual error of any sort, and you fail the assignment. The sadistic part of me likes it -- a journalist's job is to tell the truth. If you miss the mark, you've failed the public, and failed at your job for the day. Harsh but true Read More...
Computer-assisted reporting is important because of its potential for reporting and analysis. Visualization is important to present the information to readers. They both fall under the responsibilities of Ted Mellnik, database editor at the Charlotte Observer. His passion for data is as clear from a conversation with him as it is from his work Read More...
For the past week, we've been hearing a lot of media coverage focusing on issues both encouraging and discouraging, looking with excitement at the beginning of a new decade. But what captured my attention most recently was the release of unemployment figures from the end of 2009. If you look at the glass as half full, it's got to go up from here sometime soon, and if you look it as half empty, we're not starting in a strong economic place Read More...
