Treemaps for space-constrained visualization of hierarchies

Since the 80 Megabyte hard disk in the HCIL was shared by 14 users it was difficult to determine how and where space was used. 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.

A concept map typically represents ideas and information as boxes or circles, which it connects with labeled arrows in a downward-branching hierarchical structure.

yEd - Graph Editor yEd is a powerful desktop application that can be used to quickly and effectively generate high-quality diagrams. Create diagrams manually, or import your external data for analysis. Our automatic layout algorithms arrange even large data sets with just the press of a button. yEd is freely available and runs on all major platforms: Windows, Unix/Linux, and Mac OS X. The latest release is version 3.12.2 Key Features Vintage data visualization: 35 examples from before the Digital Era This is a guest post by Tiago Veloso, the founder of Visual Loop, a collaborative digital environment for everything related to information design and data visualization. He lives in Brazil, and you can connect with him online on Twitter and LinkedIn. If you follow us regularly on Visual Loop, you’ve probably noticed we like to featured not only modern interactive visualizations and infographics, but also examples from the past, from the time when there were no computer softwares to help analyzing and designing and no Internet to access and share data.

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. Data Visualization: Top 20 Amazing Tools It’s often said that data is the new world currency, and the web is the exchange bureau through which it’s traded. As consumers, we’re positively swimming in data; it’s everywhere from food labels to World Health Organisation reports. As a result, for the designer it’s becoming increasingly difficult to present data in a way that stands out from the mass of competing data streams. MR5RZMKG9XBF One of the best ways to get your message across is to use a visualisation to quickly draw attention to the key messages, and by presenting data visually it’s also possible to uncover surprising patterns and observations that wouldn’t be apparent from looking at stats alone. As author, data journalist and information designer David McCandless said in his TED talk: “By visualising information, we turn it into a landscape that you can explore with your eyes, a sort of information map.

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 20 free data visualisation tools In this article, I want to focus on tips and tools that are free and easily accessible. There are loads of great paid tools out there, and I use many of them. But it is hard to expect someone just getting into this field to pay for expensive software without actually knowing what they are getting into. This article looks to expand the list to even more tools and resources you can use to help you get started creating beautiful data visualisations for the web and print.
