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


python -h

View results in browser

This is an exemplary workflow for tests :

  • Download the repository

  • Simplify your data

    python -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
