Focus node explorer with d3.js - Excel Liberation There's a lot of different things going on in this topic. Most of them have been covered before, and lead to this mashup, but I am introducing a new kind of d3 chart (for me anyway) - I'm calling it a force directed node focus chart. It's kind of a collapsible force directed (as shown by Mike Bostok here), but no quite. Not quite a tree The data to be shown is generated by Google Apps Script from a Google Site, as shown in Analyzing site content with GAS. For a collapsible force directed chart, the data would need to be in a tree format - so for example that would work for visualizing a the layout of the pages of a site, but in this case, I'm using data that shows the relationship between topics and the pages they are referenced from - that means that each topic can appear on multiple pages, and of course multiple pages can cover multiple topics.
How sensor journalism can help us create data, improve our storytelling Data journalism, meet sensor journalism. You two should talk. What’s sensor journalism? I’ll get to that. But first, let me tell you a story about bugs — and a pair of gadgets that sat for months in a box under John Keefe’s bed. Keefe, senior editor for data news and journalism technology at WNYC in New York, said by phone that he had bought the Arduino microcontroller and Raspberry Pi with great excitement, played with them for a weekend, and then boxed them up.

Health and Wealth of Nations - Cesium - WebGL Virtual Globe and Map Engine Alexander Wood and Ed Mackey from Analytical Graphics, Inc. developed an app that showcases the synergy between the powerful open source visualization frameworks, D3 and Cesium. This demo is the result of a one day hackathon hosted at Analytical Graphics, Inc in April of 2013. The app repurposed Mike Bostock’s D3 recreation of Hans Roslings’ “Health and Wealth of Nations” as an interactive overlay for a Cesium geospatial view.
A Big Article About Wee Things This article was co-published with Source. The scene is total chaos: a woman and all her purse's contents in middair as she trips over a child's toy, a man hastily trying to gather his spilled laundry, a screaming child weaving through the crowd. Somewhere, in the midst of it all, is the person you've been looking for: wearing a red and white striped shirt, black rimmed glasses and a lopsided cap. There he is! There's Waldo. Many of us have fond memories of Waldo.
TAGSExplorer: Interactively visualising Twitter conversations archived from a Google Spreadsheet MASHe Graphs can be a powerful way to represent relationships between data, but they are also a very abstract concept, which means that they run the danger of meaning something only to the creator of the graph. Often, simply showing the structure of the data says very little about what it actually means, even though it’s a perfectly accurate means of representing the data. Everything looks like a graph, but almost nothing should ever be drawn as one. Ben Fry in ‘Visualizing Data’ I got that quote from Dan Brickley’s post Linked Literature, Linked TV – Everything Looks like a Graph and like Dan I think Ben Fry has it spot on.

New Map of Twitterverse Finds 6 Types of Networks COLLEGE PARK, Md. – People tweet about anything and everything, but a new Twitter analysis coauthored by University of Maryland computer scientist Ben Shneiderman shows much of this conversation falls into six distinct patterns or networks. The study analyzed tens of thousands of Twitter conversations over the past four years to reveal a "topographical map" of these patterns—each showing identifiable contours—based on the topic being discussed, the information and influencers driving the conversation and the social network structures of the participants. These six networks are: Shneiderman, a widely recognized pioneer in human-computer interaction and information visualization, co-authored the comprehensive new study with Lee Rainie, director of the Pew Research Internet Project, Marc A.
How to make your own d3 js visualisation The best way to learn d3.js is by taking apart examples One of the best ways to learn d3.js is by editing existing visuals. Below I show you how several d3 visuals can be easily edited. You can add your own data and format the code so, visually, the d3 visual looks different enough from the original. We won’t change the structure (much) of these visuals so this is a handy d3 tutorial or beginners to wet their feet with. The first visual we’ll edit is the brilliant titanic survivors graphic made here.

Please share your work on Observable, or tweet us a link! Visual Index Biology Biology is an extremely broad field of study. It includes topics that range from the domain of molecules and cells to the interactions between populations of species—and everything in between. As such, this Major accommodates a number of different career paths; you may opt to declare a major in biology if you plan to be a forensic scientist, a patent agent, a pharmaceutical researcher, or a professional in any number of related fields. At present, the field of biology has seen a rapid increase in discoveries, thanks to developments in technology and computing.
Tableau Pills: Measures and Dimensions This is the first in a three part series related to the four types of pills in Tableau. The four pill types are discrete dimension, continuous dimension, discrete measure, and continuous measure. Grasping these concepts is important to understanding Tableau and relational databases in general. This article will specifically focus on explaining the less intuitive concepts of non-numeric measures and numeric dimensions.
