Could be a fun student project. Written by Elizabeth Wolf, Fundación Ciudadano Inteligente The recent months of 2011 have marked the manifestation of student frustration with the Chilean education system. Hundreds of thousands of university and secondary students have flooded the streets of Santiago and other cities across Chile, in a series of protests demanding: lower tuition, more opportunities to access public universities, better quality education, and increased government spending on education, including more scholarships for lower class students.(( The Chilean government spends less on education than most developed countries: 4.4% of its GDP, compared to the average 7%, which means a good portion of Chilean students pay for their own university education. With the combination of being one of the most socially stratified countries in the world, (40% of the country's wealth is concentrated in 10% of the population), and the high costs of education, many students do not have the ability to attend a quality university. The Piñera administration and the leading group of Chilean students, along with their supporters have been at odds with each other for the last few months, struggling on the debate of education policy reform. Unable to agree upon a solution, the result has been the eruption of student protests across the country.((

"ReConstitution 2012, a fun experiment by Sosolimited, processes transcripts from the presidential debates, and recreates them with animated words and charts. Part data visualization, part experimental typography, ReConstitution 2012 is a live web app linked to the US Presidential Debates. During and after the three debates, language used by the candidates generates a live graphical map of the events. Algorithms track the psychological states of Romney and Obama and compare them to past candidates. The app allows the user to get beyond the punditry and discover the hidden meaning in the words chosen by the candidates. As you let the transcript run, numbers followed by their units (like "18 months") flash on the screen, and trigger words for emotions like positivity, negativity, and rage are highlighted yellow, blue, and red, respectively. You can also see the classifications in graph form. There are a handful of less straightforward text classifications for truthy and suicidal, which are based on linguistic studies, which in turn are based on word frequencies. These estimates are more fuzzy. So, as the creators suggest, it's best not to interpret the project as an analytical tool, and more of a fun way to look back at the debate, which it is. It's pretty fun to watch. Here's a short video from Sosolimited for more on how the application works: "

Enclosure diagrams are also space-filling, using containment rather than adjacency to represent the hierarchy. As with adjacency diagrams, the size of any node in the tree is quickly revealed. Although circle packing does not use space as efficiently as a treemap, the "wasted" space effectively reveals the hierarchy. At the same time, node sizes can be rapidly compared using area judgments. By flattening the hierarchy, the pack layout can also be used to create bubble charts.

How to make searchable, Web-based Google charts Michelle Minkoff by Michelle Minkoff Published June 3, 2011 12:01 am Updated June 2, 2011 10:22 pm A lot of data visualization requires the technical expertise of a programmer and skills that take time and resources to develop. A rise in free tools, however, has made it easier to make interactive graphs in charts, whether you're a designer, developer, Web producer or hobbyist. The Google Visualization API, for instance, gives you options without making the work too complicated. I've created a tutorial below to help you make simple, Web-based Google charts. (You can click on any of the screenshots to go to a larger version.) In the first example, we'll craft an interactive bar chart that compares the numbers of tornado-related deaths in the United States throughout the past four years. We'll use data from the National Oceanic and Atmospheric Administration (NOAA), which can be found here. (You can download a cleaned version of this data here, formatted as a comma-delimited file, CSV.) http://www.poynter.org/how-tos/newsgathering-storytelling/126595/how-to-make-simple-web-based-google-charts
