But I found that the classic random walk algorithm creates results that are, well…too random, as opposed to the organic, botanical shapes I was looking for. Luckily, someone has already thought of developing a “Random Walk with Transition Probabilities that Depend on Direction of Motion”… READ THE WHOLE ARTICLE ON OUR MAIN...

Inspired by the work of Noah Salvaterra and his beautiful Tableau visualizations of fractals and L-Systems, I made this visual of the Lorenz Strange Attractor. Edward Lorenz, a meteorologist and mathematician,  developed a set of equations to model atmospheric convection. When plotted in 3-dimensional space, the equations generate a beautiful pattern. If you want to know more, here is a nice introduction to Chaos Theory. How did I make the plot in Tableau? I used Processing to generate the points (see code below) but this could could as easily be done in Excel. PrintWriter textFile; //set parameters float h=0.008;...

Do you know what pointillism is? It’s a technique of painting with small distinct dots to create an image. And you can do this with Tableau! Well, sort of. READ THE WHOLE ARTICLE ON OUR MAIN...
