Data VisualizationTutorials KDMC produces a wealth of digital media tutorials to support our training sessions and classes. While the focus of some tutorials is on technology and journalism, most are general enough to be of use to anyone. Spreadsheets Updated March 11, 2012 in Data Visualization This tutorial covers the basics of creating and doing calculations with a spreadsheet. It is based on using Google Docs spreadsheets, with notes on some differences with Excel spreadsheets.
Who's Alive and Who's Dead: Living Members of the Baseball Hall of Fame The Baseball Hall of Fame can include players, managers, umpires, and executives (Most managers were former players and many players later become managers, but they are usually voted into the Hall as one or the other, as their career merits). The baseball writers association has the primary responsibility for selecting which players will be in the Hall of Fame. Players who are no longer under consideration by the baseball writers can be voted in by the veterans committee. The veterans committee is viewed by many as a "back door" into the Hall and, therefore, it is considered more prestigious to be inducted by the baseball writers. The veterans committee - known since 2011 as the "historical overview committee" - is also responsible for inducting non-players, including managers, executives, and umpires. The list below gives each living Hall member, in order of date of birth.

10 Steps To Designing An Amazing Infographic Information can be useful—and even beautiful—but only when it’s presented well. In an age of information overload, any guidance through the clutter comes as a welcome relief. That’s one reason for the recent popularity of information graphics. Infographics are visual designs that help to explain complicated data in a simple way (mental-health emergencies at Burning Man, anyone?). But how are they created?
Frontiers of Computational Journalism In this week’s class, we discussed clustering algorithms and their application to journalism. As an example, we built a distance metric to measure the similarity of the voting history between two members of the UK House of Lords, and used it with multi-dimensional scaling to visualize the voting blocs. The data comes from The Public Whip, an independent site that scrapes the British parliamentary proceedings (the “hansard“) and extracts the voting record into a database. The files for the House of Lords are here. Can Someone :help Me? Vim has the best documentation ever available for a software product. No other software product that I've ever come across or used has had a better documentation. For my first ever blog post, I thought I would explore Vim's extensive documentation and how to start using it effectively. Newcomers to Vim don't seem to use it enough but Vim's :help can be incredibly useful.
Hyperbolic tree A basic hyperbolic tree. Nodes in focus are placed in the center and given more room, while out-of-focus nodes are compressed near the boundaries. Focusing on a different node brings it and its children to the center of the disk, while uninteresting portions of the tree are compressed. One approach is to use a hyperbolic tree, first introduced by Lamping et al. Hyperbolic trees employ hyperbolic space, which intrinsically has "more room" than Euclidean space. For instance, linearly increasing the radius of a circle in Euclidean space increases its circumference linearly, while the same circle in hyperbolic space would have its circumference increase exponentially.
My next ebook: the Data Journalism Heist In the next couple of months I will begin publishing my next ebook: Data Journalism Heist . Data Journalism Heist is designed to be a relatively short introduction to data journalism skills , demonstrating basic techniques for finding data, spotting possible stories and turning them around to a deadline. Based on a workshop, the emphasis is on building confidence through speed and brevity , rather than headline-grabbing spectacular investigations or difficult datasets (I’m hoping to write a separate ebook on the latter at some point). If you’re interested in finding out about the book, please sign up on the book’s Leanpub page .
