Data Driven Journalism Originally published by Andy Kirk on Visualising Data, 1 May 2011. This article is republished with permission. This is the fourth part of a multi-part series designed to share with readers an inspiring collection of the most important, effective, useful and practical data visualisation resources. 1. Introduction Step-by-step instructions for making maps This crash course walks through how to design custom web maps in TileMill. It will help you quickly get familiar with the basics of map design with TileMill, from importing and styling your data to designing and sharing your map. This guide focuses on the core functions of TileMill and links to documentation throughout for more advanced and specific techniques in map design. Start here for an overview of TileMill.

2010 Census: Children less than five years old in Chicagoland By Chris Groskopf and Brian Boyer Aug. 7, 2011 This map shows the distribution of children less than five years old in Cook, Lake, Kane, McHenry, Kankakee, Kendall and DuPage counties as reported by the 2010 U.S. Census. Each dot represents a single child Thinkmap SDK The Thinkmap SDK enables organizations to incorporate data-driven visualization technology into their enterprise Web applications. Thinkmap applications allow users to make sense of complex information in ways that traditional interfaces are incapable of. The Thinkmap SDK (v. 2.8) includes a set of out-of-the-box configurations for solving common visualization problems, as well as new visualization techniques for customizing data displays. We have designed Thinkmap to be lightweight, fast, easily extensible, and able to connect seamlessly to a wide variety of data sources. Thinkmap is composed of two primary components:

Life Below 600px Some people would have you believe that you aren't reading this. Why? Because it's not 'above the fold'. How To Build an Interactive Map with Open-Source Tools My interactive migration map for Forbes, showing inbound (blue) and outbound (red) migration to and from Maricopa County, Arizona My latest interactive migration map on improves on the previous version in a few ways: it’s got five years of data instead of one; a brand-new layout; and some much-requested features like a search tool and the ability to switch off the lines. But the upgrade that I’m most excited about is in the code: I built the map using nothing but open-source software, from Python and MySQL to handle the data right down to JavaScript to display the map. I’ve been steadily moving much of my data handling to Python and MySQL, but this is the first map I’ve made using JavaScript, and interactive JS maps are still rare elsewhere, too.

The Insanely Illustrated Guide To Your First Data-Driven TileMill Map TileMill is a free-to-download application for Windows and the Mac that will let you build beautiful, data driven maps. If the bland sameness of Google maps is giving you ennui, TileMill might be a good alternative for you. There are many beautiful stylesheets to make TileMill maps visually distinct, and you can control the colors, line widths, and much more about your map using Carto, a CSS-derived language. Here’s a beautiful map of Montreal using a watercolor-like stylesheet: What follows is a detailed, highly-illustrated guide to creating your first map in TileMill.

Better web cartography with dot density maps and new tools « News Apps Blog Between Brian, Joe, and myself there hasn’t been a time in the last six months where at least one of us wasn’t working with census data. Back in February we attacked the less-detailed (redistricting) data for print and the web. In April, May, and June we contributed to a joint effort with an esteemed cadre of news nerds to develop, a site intended to make it easier for journalists to report from census data. And to prepare for this recent release, we even spent a week hacking near-complete prototype maps using data that the census had already released, Kings County, New York. We learned hard lessons about the scale and nuance of the census in the last few months, and along the way, further built out our toolkit for making maps. Last week the Census Bureau released detailed (summary file) data for Illinois, and we used our new tools to produce a couple of maps we’re pretty excited about:
