Eurozone debt web: Who owes what to whom? The circle below shows the gross external, or foreign, debt of some of the main players in the eurozone as well as other big world economies. The arrows show how much money is owed by each country to banks in other nations. The arrows point from the debtor to the creditor and are proportional to the money owed as of the end of June 2011.
The colours attributed to countries are a rough guide to how much trouble each economy is in. Click on a country name to see who they owe Europe is struggling to find a way out of the eurozone crisis amid mounting debts, stalling growth and widespread market jitters. After Greece, Ireland, and Portugal were forced to seek bail-outs, Italy - approaching an unaffordable cost of borrowing - has been the latest focus of concern. But, with global financial systems so interconnected, this is not just a eurozone problem and the repercussions extend beyond its borders. So, in the tangled web of inter-country lending, who owes what to whom? 235% Foreign debt to GDP. Memory techniques.
Knowledge Models / Concept Mapping. Concept map. Diagram showing relationships among concepts A concept map or conceptual diagram is a diagram that depicts suggested relationships between concepts.[1] Concept maps may be used by instructional designers, engineers, technical writers, and others to organize and structure knowledge. Differences from other visualizations [edit] Novak's work is based on the cognitive theories of David Ausubel, who stressed the importance of prior knowledge in being able to learn (or assimilate) new concepts: "The most important single factor influencing learning is what the learner already knows. Ascertain this and teach accordingly. Concept maps are used to stimulate the generation of ideas, and are believed to aid creativity.[4] Concept mapping is also sometimes used for brain-storming.
Formalized concept maps are used in software design, where a common usage is Unified Modeling Language diagramming amongst similar conventions and development methodologies. Concept map based vs. web page based interfaces for searching and browing. Infographic. Information graphics or infographics are graphic visual representations of information, data or knowledge intended to present complex information quickly and clearly.[1][2] They can improve cognition by utilizing graphics to enhance the human visual system’s ability to see patterns and trends.[3][4] The process of creating infographics can be referred to as data visualization, information design, or information architecture.[2] Overview[edit] Infographics have been around for many years and recently the proliferation of a number of easy-to-use, free tools have made the creation of infographics available to a large segment of the population.
Social media sites such as Facebook and Twitter have also allowed for individual infographics to be spread among many people around the world. In newspapers, infographics are commonly used to show the weather, as well as maps, site plans, and graphs for statistical data. "Graphical displays should: Graphics reveal data. History[edit] Early[edit] 20+ Tools to Create Your Own Infographics. A picture is worth a thousand words – based on this, infographics would carry hundreds of thousands of words, yet if you let a reader choose between a full-length 1000-word article and an infographic that needs a few scroll-downs, they’d probably prefer absorbing information straight from the infographic.
What’s not to like? Colored charts and illustrations deliver connections better than tables and figures and as users spend time looking back and forth the full infographic, they stay on the site longer. Plus, readers who like what they see are more likely to share visual guides more than articles. While not everyone can make infographics from scratch, there are tools available on the Web that will help you create your very own infographics.
In this article, we’re listing more than 20 such options to help you get your messages across to your readers, visually. Read Also: The Infographic Revolution: Where Do We Go From Here?

When to use a network diagram Real-world information often comes in the form of relationships between entities or items, such as people who know each other (social networks), or Web pages that are connected to each other. In a network diagram, entities are connected to each other in the form of a node and link diagram. How network diagrams work A network consists of a set of objects called vertices connected by edges.
The network display in Many Eyes is fully interactive and can be zoomed and panned to obtain a detailed view of different sections of the graph: Pan : Drag using the right mouse button to view a different area of the graph. And buttons on the bottom to zoom in and out. View reset button. Selection : To highlight nodes, select them with the left mouse button.
Button at the bottom of the screen. Direction : If the direction of links is relevant to your dataset you can toggle arrowheads on edges by clicking the button. Data requirements. The Infographic Revolution: Where Do We Go From Here? The infographic may seem to some to be a modern phenomenon; but not many know of the true origins and purpose of an infographic. For one thing, it isn’t an invention of the digital medium, it is merely popularized by it. In this article I will be examining the origins of an infographic and how it is more popularly used today. We will take a step back and look at how the data used in these infographics truly enhancing our user experience, and study how much of it is really newsworthy. The Birth of the Infographic The are effective, that is for sure. As I mentioned earlier, infographics are not something new, in fact it has already been put to good use, in print, centuries before.

Public Data Explorer. DSPL Tutorial - DSPL: Dataset Publishing Language. DSPL stands for Dataset Publishing Language. Datasets described in DSPL can be imported into the Google Public Data Explorer, a tool that allows for rich, visual exploration of the data. Note: To upload data to Google Public Data using the Public Data upload tool, you must have a Google Account. This tutorial provides a step-by-step example of how to prepare a basic DSPL dataset. A DSPL dataset is a bundle that contains an XML file and a set of CSV files. The CSV files are simple tables containing the data of the dataset.
The XML file describes the metadata of the dataset, including informational metadata like descriptions of measures, as well as structural metadata like references between tables. The metadata lets non-expert users explore and visualize your data. The only prerequisite for understanding this tutorial is a good level of understanding of XML. Contents Overview Before starting to create our dataset, here is a high-level overview of what a DSPL dataset contains: Defining Concepts. Downloads - dspl - Dataset Publishing Language. Google Opens Up Infographic Tools for Everyone's Use. A great data for data geeks of all stripes: Today, Google has opened up the tools on its Public Data Explorer, so that you can use them to chart any old data set you might have laying around.
"If you're a student or a journalist or a teacher, you can upload your data and get the same visualizations that we have for our own product," Ben Yolken, Google's product manager for the Public Data Explorer, tells Co.Design. The tools were first rolled out a year ago, after the company bought up the Gapminder Trendalizer, a bubble-chart data-viz technology invented by Dr. Hans Rosling, the infographics guru/health researcher/acclaimed TED genius. [Dr. Rosling showing off the Gapminder Trendalyzer, upon which Google's Public Data Exporer is based] [Dr Rosling show how rich the tools are] Now, to use all these nifty charts, you just have to put your data into a special format developed by Google, which is adapted to each of these visualizations.
