Guess which link-map representation above is the most efficient for showing directionality? Information Aesthetics blog has an interesting article about the different techniques for showing the “from-” and “to-” of network charts.
Networks are often visualized using points and interconnecting lines, with triangular arrowheads at one or both ends to show any directionality between the different points. Although such a standard arrow representation seems intuitive, it can lead to problems in dense graphs that contain many incoming or outgoing relationships. Furthermore, since the arrowheads often have approximately the same size and aspect ratio as the small circles they connect, the graph as a whole might be perceived as cluttered with so much visual detail to the point of being distracting.

How many different user interfaces can you create for something completely banal? Read 1,000 Screens, 1,000 Dreams over on World Famous Design Junkies to see how something as simple and commonplace as scorekeeping for bowling can be complexified endlessly. Dozens of screenshots show the variations that can occur when you need to record a few columns and rows of numbers. What if this data was more complex?
Posts like this make me think that we’re only scratching the surface for Big Data visualization. How many ways can you envision a social network such as a series of cell phone calls? How soon before we transcend the boring lines-and-icons approach?
