These links load their settings from a JSON parameter file (?paramfile=examples/…json). The browser fetches that file, so this only works when the pages are served by a web server, not from file://. Locally you can run python3 -m http.server 9001 -d pub, or start Chrome with --allow-file-access-from-files.
