title: Plotting quadtree outline in gnuplot
body: <p>I have a quadtree like structure in my code, which I want to visualise in gnuplot. This means I want to see the rectangular subdivisions. The reason why I would like to have this in gnuplot is because I want to plot a 2d function over this outline to show correlations between the amount of subdivisions and the function value.</p>
  
  <p>Does ayone have an idea on how to do this?</p>
