This paper presents an interactive physics-based technique for the exploration and dynamic reorganization of graph layouts that takes into account semantic properties which the user might need to emphasize. Many techniques have been proposed that take a graph as input and produce a visualization solely based on its topology, seldom ever relying on the(More)
This paper introduces an interactive system called GraphCuisine that lets users steer an Evolutionary Algorithm (EA) to create random graphs that match user-specified measures. Generating random graphs with particular characteristics is crucial for evaluating graph algorithms, layouts and visualization techniques. Current random graph generators provide(More)
MagnetViz was designed for the interactive manipulation of force-directed graph layouts, allowing the user to obtain visualizations based on the graph topology and/or the attributes of its nodes and edges. The user can introduce virtual magnets anywhere in the graph and these can be set to attract nodes and edges that fulfill user-defined criteria. When a(More)
Graphs are widely utilized in many fields and several applications require their visualization. Graph visualization is based on techniques for graph drawing, interaction and navigation in such a way that helps the user in finding and manipulating information efficiently. These techniques, which can be two or three-dimensional, depending on the spatial(More)
We present a scientific reflection on the creation of a large illustrative personal data graphics that we create to mimic 18th–19th century style visualizations. We discuss the relationship to illustrative visualization, the story-telling aspects of the design, the used data sources and their purpose, the creation of the overall style, and the aspects of(More)
A stock market investor relies on two schools of analysis of market behavior to determine a trading strategy: Technical Analysis and Fundamental Analysis. Fundamental Analysis is based on the study of the fundamental data of a company and more directed to long-term investments, not taking into account small short-term price oscillations. On the other hand,(More)
We exhibit an data graphic poster that emulates the style of historic hand-made visualizations of the 18th–19th century. Our visualization uses real data and employs style elements such as an emulation of ink lines, hatching and cross-hatching, appropriate typesetting, and unique style of computer-assisted facial drawings.
