Graph Visualization Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. Automatic graph drawing has many important applications in software engineering, database and web design, networking, and in visual interfaces for many other domains. Graphviz is open source graph visualization software. It has several main graph layout programs. See the gallery for some sample layouts. It also has web and interactive graphical interfaces, and auxiliary tools, libraries, and language bindings.

Gapminder is a non-profit venture promoting sustainable global development and achievement of the United Nations Millennium Development Goals by increased use and understanding of statistics and other information about social, economic and environmental development at local, national and global levels. Gapminder is registered as a Foundation at Stockholm County Administration Board (Länstyrelsen i Stockholm) with registration number (organisationsnummer) 802424-7721. It was founded in Stockholm by Ola Rosling, Anna Rosling Rönnlund and Hans Rosling on 25 February 2005. Gapminder does not award any grants. It is an operating foundation (verksamhets stiftelse) that implements activities as defined by the board, often as collaborative projects with universities, UN organisations, public agencies and non-governmental organisations. The initial activity was to continue development of the Trendalyzer software. This software unveils the beauty of statistical time series by converting boring numbers into enjoyable, animated and interactive graphics. The current beta version of Trendalyzer is available since March 2006 as Gapminder World, a web-service displaying a few time series of development statistics for all countries www.gapminder.org/world . In March 2006 Google acquired Trendalyzer from Gapminder Foundation and the team of developers that worked for Gapminder has joined Google in California since April 2007. Since the Trendalyzer development was taken over by Google the Gapminder Foundation maintain the same aim and uses Trendalyzer and its resources to produce videos and web service showing major global development trends with animated statistics. Such a 3 to10 minute video is called a GapCast and they are published as free web casts with the aim of promoting a fact based world view. A GapCast converts statistical time series into moving graphics in ways that allows evidence based trends to be told as simple story lines. The time series used will be made freely available in the web service called Gapminder World that enable end users to further explore the underlying statistics in Trendalyzer graphics. The present staff of Gapminder consist of Hans Rosling, Director, Straffan Landin, web producer [ staffan.landin@gapminder.orgThis e-mail address is being protected from spam bots, you need JavaScript enabled to view it ] Mattias Lindgren, statistics manager [ mattias.lindgren@gapminder.orgThis e-mail address is being protected from spam bots, you need JavaScript enabled to view it ]
