New pages from Beautiful Evidence: Causal arrows and linking lines—Feynman diagrams, epidemiological diagrams

“Here is a draft of what might well be the 4 concluding pages to the chapter in ‘Beautiful Evidence’ on causal arrows and linking lines. A few other parts of the chapter were posted earlier (on the Barr art chart, on evolutionary trees and cladistic diagrams). After this new material is reviewed by Kindly Contributors, then perhaps the full 16-page chapter will at last be ready to post.” (Edward Tufte) – courtesy of xblog

A subway map of cancer pathways

“Cancer arises from the stepwise accumulation of genetic changes that confer upon an incipient neoplastic cell the properties of unlimited, self-sufficient growth and resistance to normal homeostatic regulatory mechanisms. Advances in human genetics and molecular and cellular biology have identified a collection of cell phenotypes — the main destinations in the subway map — that are required for malignant transformation. Specific molecular pathways (subway lines) are responsible for programming these behaviours.” (William C. Hahn and Robert A. Weinberg – Nature)

Understanding visual communication

“They say that a picture is worth a thousand words. Indeed, some pictures are better at conveying some things than words. Still, not all pictures are created equal, and the power of visual communication is sometimes misunderstood, if not misused. Pictures are no panacea; some words may well convey concepts better than a thousand pictures, too.” (Jean-luc Doumont – STC Belgium)

The Vision of George Rorick

“Architect of six different news services for print and broadcast graphics, George has spent his career fine-tuning the craft of visual reporting, discovering talented people and starting business from scratch. Oh … and he invented the USA Today weather map. Find out what makes him tick and what he’s done for the field of visual journalism.” (Poynter online) – courtesy of interactive narratives

Automating the Design of Visual Instructions

“Visual instructions are a common part of our daily lives. Maps, training manuals, textbooks, architectural plans, scientific papers, and street signs all use visual diagrams to communicate instructions. Yet, even the simplest visualizations typically take hours or days to design by hand, and therefore it is not currently possible to adapt and personalize instructions to the task, person, and situation for which they are eventually used. In contrast, while current computer-generated visualizations can be generated very quickly, these systems disregard many of the cognitive design principles that guide human designers. As a result current computer-generated visualizations can be very difficult to use.” (Maneesh Agrawala) – courtesy of yuri engelhardt

Generating Explanatory Captions for Information Graphics

“This paper presents three strategies for generating explanatory captions to accompany information graphics based on: (1) a representation of the structure of the graphical presentation (2) a framework for identifying the perceptual complexity of graphical elements, and (3) the structure of the data expressed in the graphic.” (Vibhu O.
