Graphael: A System for Generalized Force-Directed Layouts

Abstract: Abstract. The graphael system implements several traditional forcedirected layout methods, as well as several novel layout methods for non-Euclidean geometries, including hyperbolic and spherical. The system can handle large graphs, using multi-scale variations of the forcedirected methods. Moreover, graphael can layout and visualize graphs that evolve though time, using static views, animation, and morphing. The implementation includes a powerful interface that allows the user to put together existing algorit… Show more

“…Creating smooth animation between changing sequences of graphs is addressed using spectral graph visualization in [15]. When using the animation/morphing approach, it is possible to change the balance between readability of individual graphs and the overall mental map preservation, as in the system for Graph Animations with Evolving Layouts, GraphAEL [35,40]. Applications of this framework include visualizing software evolution [24], social networks analysis [9], and the behavior of dynamically modifiable code [30].…”

“…Several techniques generate incremental node-link drawings that show the graph evolution by optimizing a cost function that combines classical static-graph-drawing aesthetic criteria with maximizing the layout stability of unchanging graph parts [15,13,14,20]. Animation can be preferable to smallmultiples in conveying dynamic patterns, especially for long repetitive time series [39].…”

“…Since we did not have actual sensors to work with, we wrote a plugin for our graph visualization system, Graphael [5], that simulates the placement of the sensors and the reported information from each. Our sensor data generator takes the following parameters as input: number of sensors, average connectivity (density), region to place the sensors in (square-shape, star-shape, etc.…”
