Marek Otahal and I have been working on a simple tool to aid in the visualization of CSV files, such as might be output by the OPF. We created a NuPIC Community repository for the project: https://github.com/nupic-community/nupic.visualizations
Feel free to use, create issues, or contribute to the project. I hope that some people find it useful. We will be continuing to work and refine the project. Cheers, Jeff
