The concept of rectangle-of-influence (RI) drawings is old and well-studied in the area of graph drawing. A graph has such a drawing if we can assign points to its vertices such that for every edge (v, w) the supporting rectangle (i.e., the minimal closed axis-aligned rectangle R(v, w) containing v and w) contains no other points. In the original setup, the graph had to have an edge for every p...

We propose a method for visualizing a set of related metabolic pathways using 2 2D graph drawing. Interdependent, twodimensional layouts of each pathway are stacked on top of each other so that biologists get a full picture of subtle and significant differences among the pathways. Layouts are determined by a global layout of the union of all pathway-representing graphs using a variant of the pr...

ForceAtlas2 is a force vector algorithm proposed in the Gephi software, appreciated for its simplicity and for the readability of the networks it helps to visualize. This paper presents its distinctive features, its energy-model and the way it optimizes the “speed versus precision” approximation to allow quick convergence. We also claim that ForceAtlas2 is handy because the force vector princip...

This article describes the application of functional programming techniques to a problem previously studied by imperative programmers, that of drawing general trees automatically. We rst consider the nature of the problem and the ideas behind its solution (due to Radack), independent of programming language implementation. We then describe a Standard ML program which reeects the structure of th...
