Visualization

We provide a Web interface for visualizing the execution of a sequential Monte Carlo algorithm, based on contributions from Maddy Bowers and Jacob Hoover.

First, update your model to support visualization by implementing the string_for_serialization method. Return a string that summarizes the particle's current state.

To run the interface, change to the html directory and run python -m http.server. This will start serving the files in the html directory at localhost:8000. (If you are SSH-ing onto a remote machine, you may need port forwarding. Visual Studio Code automatically handles this for some ports, including 8000.) Then, when calling smc_standard, set visualization_dir to the path to the html directory. A JSON record of the run will automatically be saved to that directory, and a URL will be printed to the console (http://localhost:8000/smc.html?path=$json_file).
