This is an exemplary workflow for tests :

• Download the repository

• Simplify your data

  python simplify.py -i in.json -o out.json -t 0.0005

• setup local server (necessary for D3.js)

  python -m SimpleHTTPServer 8888

• open in browser: http://localhost:8888/index.html

• If needed adjust the filenames within the example/index.html (lines 24 & 28)

• evaluate the resulting data and try another threshold
