As a child of the 80s, the Choose Your Own Adventure books were a fixture of my rainy afternoons. My elementary school library kept a low, fairly unmaintained-looking shelf of them hidden in one of its back corners. Whether this non-marquee placement was an attempt by the librarians to deemphasize the books in favor of ‘serious’ (children’s) literature or was simply my good luck I still haven’t worked out.
Given a bitmap image of a chart, ReVision applies computer vision methods to identify the visualization type, extract the underlying data, and generate redesigned visualizations.

Jeffrey Heer , Stanford Computer Science (HCI) jheer stanford.edu In this talk, I will chart the course of visual depictions of data over the last 200 years, from the classic data graphics of Playfair and Minard to modern interactive visualization systems. Along the way, we will consider the factors that contribute to the effectiveness of information graphics and the role of computational tools in the visualization process. I will conclude with a review of current research directions in interactive visualization and suggest opportunities for future investigation.
Forrester says: Sales enablement is a strategic, ongoing process that equips all client-facing employees with the ability to have a valuable conversation with the right set of clients. IDC says: Sales enablement is the delivery of the right information to the right person at the right time and in the right place. We say: Sales enablement delivers methods, processes and tools which ensure that your organization's sales people are equipped with the knowledge they need to win deals.

Treemap quick tutorial at noumena
You could change the main container id by setting the rootId property to whatever id you like in the controller object passed to the TM constructor. Colors are calculated by taking the second dataset object value. You must also know the range of this value. In this example the second value ranges between [-100, 100]. You can change these values by setting the Color.minValue and Color.maxValue parameters for the treemap controller.
Government defense spending rose in the first quarter -- or it fell, depending on where you look. The year-on-year growth rate in the Treasury Department compares to a drag from the GDP report. Analysts say it's unlikely defense spending will fall 8% for the full year.

These are examples of Stamen's research projects. Experimental and client work have a way of feeding into one another: the crossover process enriches both. Stamen doesn't believe in a clear separation between ideas and technology, or between client work and research work. For us, they're intermingled, and we look for ways to enrich our work and play with whatever new tools become available.

Treemaps for space-constrained visualization of hierarchies
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. 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. Finding large files that could be deleted, or even determining which users consumed the largest shares of disk space were difficult tasks. Tree structured node-link diagrams grew too large to be useful, so I explored ways to show a tree in a space-constrained layout. I rejected strategies that left blank spaces or those that dealt with only fixed levels or fixed branching factors. Showing file size by area coding seemed appealing, but various rectangular, triangular, and circular strategies all had problems.Blog Archive » Information Visualization for Knowledge Discovery
Treemap developed by Jean-Daniel Fekete Ben Schneiderman from the University of Maryland, gave a fascinating talk in Cambridge on 5th March 2009 about the topic of “Information Visualization for Knowledge Discovery.” Ben has authored many books and papers on human computer interaction, and was the founder of the Human Computer Interaction Laboratory at the University of Maryland. His keen interest is the field of information visualisation. During his talk, Ben pointed out that in contrast to scientific visualization information visualization is a relatively young field as information visualization conferences have only been going for about 15 years.The great thing about Realmac’s QuickSnapper site is that if JavaScript is turned off, the list of snaps is visible by default. So we’ll follow suit. It’s also worth noting that their version only keep pulling in new items until it hits the end. I’ll show you how you can keep the list looping, and in a follow up tutorial I’ll show you how to hook this in to an Ajax hit that doesn’t hammer your server and keeps the effect nice and smooth. This allows me to reference the $ variable knowing that it won’t conflict with other libraries such as Prototype - because we’ve passed the jQuery variable in to the function in the following line:
