Visual Recurrence Analysis (VRA) is a free software package for topological analysis, qualitative and quantitative assessment, and nonparametric prediction of nonlinear and chaotic time series. The software runs under Windows 95/98/ME/2000/NT/XP. The latest version is 5.01, released in May 2007.

  
Two examples of a recurrence plot, as they look in VRA. On the left is Lorenz attractor, embedded in the three-dimensional phase space. On the right is the standard human limb lead II electrocardiogram.
