FreeMind Visual complexity We might commonly say we live in a complex and interconnected world, and even though this tends to be a fairly consensual statement, there's no better way to grasp the extend of nature's convolutedness than to look at the interdependency of its innumerous ecosystems. The images shown here are renderings of the metanetwork for the San Francisco Bay food web. The network consists of 163 nodes, each node being a guild. In total, they represent approximately 1,600 species of invertebrates and fish, as well as four nodes representing various types of autotrophic producers. There are 5,024 links or trophic interactions between the guilds. The dataset currently excludes birds and marine mammals. The second image, representing the same metanetwork, uses a different drawing algorithm, which arranges guilds hierarchically instead of in a circular fashion. As Rachel Hertog's professor Peter D.
Treemaps for space-constrained visualization of hierarchies Started Dec. 26th, 1998 by Later updates by Ben Shneiderman and Catherine Plaisant - Last update Sept 2014 Our treemap products: Treemap 4.0: General treemap tool (Free demo version, plus licensing information for full package) PhotoMesa: Zoomable image library browser (Free demo version, plus licensing information for full package) Treemap Algorithms and Algorithm Animations (Open source Java code) A History of Treemap Research at the During 1990, in response to the common problem of a filled hard disk, I became obsessed with the idea of producing a compact visualization of directory tree structures. Tree structured node-link diagrams grew too large to be useful, so I explored ways to show a tree in a space-constrained layout. My initial design simply nested the rectangles, but a more comprehensible design used a border to show the nesting. My excitement about treemaps was great and like many innovators I thought millions of users would be using this tool within a few years.

Best Infographics Ideas and Free Tools Look at pretty much every blog, professional site and presentation these days, and you will notice that most of them have infographics, which are charts that display a visual image in order to supply data to the user. They are highly functional and often work more effectively than graphs and charts alone. They are also more pleasing to the eye and can break down concepts for easier understanding. But for every good one, there is a bad one that looks cluttered and doesn’t manage to get the point across. Here are some of the best examples and tools to assist you in creating your own. Inspiration Online Piracy With new legislation being argued right now in the Senate to curb piracy, there is a lot of misunderstanding about the topic itself. It illustrates that popular movies are not affected in profit by illegal downloading. Calorie Intake & Outtake There are plenty of charts out there about food intake for dieters to keep track of their calories. How Coffee Affects the Global Economy Tools
Enterprise Software Doesn't Have to Suck: Social Network Analysis using R and Gephis After learning the basics of R, I decided to learn something harder last week. I picked Social Network Analysis (SNA) to learn the concepts of SNA and R. My primary interest in SNA is visual exploration of networks, so I needed to find a tool first. Which tool to use for visual SNA? Features needed: 1) graphical representation of network 2) visually navigate the graph (zoom in/out, drag) to explore large graphs 3) manipulate the graph (filter nodes, edit/delete/group nodes and same for edges) 4) free, preferably open source. I found out that R has good libraries like SNA (checkout Drew Conway's tutorial) and iGraph (see this tutorial) for social network analysis. So I continued my hunt for a good tool for visual SNA and discovered Gephis, an open source app for visual exploration. WARNING: SNA with Gephis is addictive. After you download Gephi, checkout Gephi quick start guide to get your bearings. Gephi Features Tour from gephi on Vimeo. Web rendition of these graphs is also possible.

Survey of Requirements Tools Lists | The Making of Software For the February 2014 update of our list of requirements management (RM) tools, my colleague Gerald Heller and I researched for other lists of requirements tools, in order to extend and complement our collection. In the following you find the results of our investigation. Each list has its specific strengths and focus areas that are outlined in brief comments on each entry. Requirements Management Tools INCOSE’s RM Tools List ( has been the first large RM tools list we know of that was researched systematically. Volere’s RM Tools List: Iain Alexander’s ’s RM Tools List at includes many tools that are not contained in INCOSE’s and Volere’s collections. The Tools Journal’s RM Tools List ( is another list that provides a good overview of tools. Ideation Tools Agile Tools Business Modeling Tools UML Tools
