## What Visualization Tool/Software Should You Use? – Getting Started

Are you looking to get into data visualization, but don't quite know where to begin?
A directed graph. In mathematics, a directed graph or digraph is a graph , or set of nodes connected by edges, where the edges have a direction associated with them. In formal terms a digraph is a pair

## Visualisation of Live Code « Alex McLean

I wrote a paper with Dave Griffiths and Nick Collins on the visualisation of live code, exploring ideas around live coding interfaces, accepted for the EVA London 2010 conference in July. A HTML version is below, or see the PDF Preprint . Alex McLean (Goldsmiths), Dave Griffiths (FoAM), Nick Collins (University of Sussex) and Geraint Wiggins (Goldsmiths)
Any web, including more especially the world wide web as a whole, is composed of pages (which we'll call nodes ) and links between them (which we'll call arcs ). This means that, from a mathematical standpoint, we can consider the structure of any website as a graph . Consequently, in order to represent the structure of a website we simply need to draw a graph .

## Kaleidoscopic (escape time) IFS

Hello, Here are some renderings of a class of fractals which I call "Kaleidoscopic IFS". There is a big variations of shapes one can get with this method. I began with this algorithm to get DE for symmetric Sierpinski tetrahedron: Then I added a rotation before the fold or before the stretch or both. //scale=2 //bailout=1000 sierpinski3(x,y,z){ r=x*x+y*y+z*z; for(i=0;i<10 && r<bailout;i++){ rotate1(x,y,z); if(x+y<0){x1=-y;y=-x;x=x1;} if(x+z<0){x1=-z;z=-x;x=x1;} if(y+z<0){y1=-z;z=-y;y=y1;} rotate2(x,y,z); x=scale*x-(scale-1); y=scale*y-(scale-1); z=scale*z-(scale-1); r=x*x+y*y+z*z; } return (sqrt(r)-2)*scale^(-i);//the estimated distance }

## PWGL - PWGL

PWGL is a visual language based on similar concepts than PatchWork.
New layout engine The new Graphviz-based layout engine built into OmniGraffle 5 allows for faster and more varied automatic layout types.
