Recently, the New York Times featured a bubble chart of the proposed budget for 2013 by Shan Carter . As FlowingData commenters point out , the use of bubbles may or may not be the best way to display this dataset. In this post, we attempt to tease out some of the details of how this graphic works. #Simple Animated Bubble Chart In order to better understand the budget visualization, I’ve created a similar bubble chart that displays information about what education-based donations the Gates Foundation has made. You can see the full visualization here And the visualization code is on github **Warning Coffeescript** The example is written in [CoffeeScript]( as I find it much easier to read and write than javascript. #D3’s Force Layout #nodes #gravity #alpha
Timeline Tutorial: Setting Up Your Spreadsheet In Google Docs Part One: Setting Up Your Spreadsheet in Google Docs We are going to host the data that will populate your timeline within Google Docs. Why this particular application? One reason to use Google is that it is free. The following seven steps will tell you how to format your spreadsheet to make it readable for the Exhibit script that powers your timeline. 1. First, you need to create some titles for your spreadsheet's columns. Your spreadsheet should now look something like this. 2. This step is very important: Select all the columns. If you don't set the columns to plain text, the spreadsheet may reformat your information. 3. Of course, if you've added additional columns to suit your needs such as the {intials} column, you can simply add text or links into the column by modelling what you've done here. 4.

How chat app giant Tencent big by correctly predicting that email was totally wrong for China — Quartz It’s a familiar story for students or businessmen on their first-ever visit to China. After rounds of beer and baijiu with potential clients, or a karaoke gathering through a university exchange program, the foreigner will ask the Chinese person sitting next to her for his email address. The Chinese person will smile blankly, somewhat confused. The Chinese person will take a few seconds to remember his email address. In many parts of the world, email remains deathless—a relic of the desktop-era internet, before mobile and social media were on the landscape. In China however, email never reached the ubiquity it has in other countries. When asked why, most Chinese or expats will simply point to WeChat. But WeChat’s present-day popularity only tells part of the story.

But another factor helped drive QQ’s popularity.
W3Schools Online Web Tutorials D3js Voici le premier d’une longue lignée (je l’espère) de tutoriaux en français portant sur la librarie d3.js. Pour en savoir plus sur cette librairie reportez vous à la présentation que j’en ai faite sur ce post. L’objectif de ce premier tutoriel est de faire quelques exemples d’utilisation très simple de la librairie. A l’instart de Jquery, d3.js est une librarie qui permet de manipuler le DOM. Mais là où d3.js est très efficace est dans la manipulation de SVG. Manipuler ou créer une div avec d3.js Ajouter et manipuler un rectangle SVG Dessiner plusieurs éléments dans un groupe svg Gérer des données au format JSON et dessiner en fonction de ces données Dans ce dernier exemple, nous allons construire des nodes qui sont en fait des groupes svg ayant la class “node”. Le dernier exemple introduit plusieurs nouveaux concepts : selectAll(), data(), et enter(). selectAll() data() La methode data() permet de “binder” (attacher) des données à des éléments sélectionnés par la methode selectAll(). enter()
