Using pyvis 0.3.2

Steps to reproduce:

# script.py
from pyvis.network import Network
nt = Network(
    cdn_resources="local",
)
nt.show('network.html', notebook=False)

The output draws content from

niko@niko-ubuntu:~/tmp/pyvis_tests$ cat network.html | grep 'href=\"http\|src=\"http' -C 5
<html>
    <head>
        <meta charset="utf-8">

Notes

Note that it pyvis actually copies these files under lib:

niko@niko-ubuntu:~/tmp/pyvis_tests$ python -m seedir 
pyvis_tests/
├─network.html
├─script.py
└─lib/
  ├─vis-9.1.2/
  │ ├─vis-network.min.js
  │ └─vis-network.css
  ├─bindings/
  │ └─utils.js
  └─tom-select/
    ├─tom-select.complete.min.js
    └─tom-select.css

The files are:

  • vis-network.min.js -- copied, but the HTML reads it from CDN
  • vis-network.css -- copied, but the HTML reads it from CDN
  • utils.js -- correct
  • tom-select.complete.min.js -- copied, but is it used?
  • tom-select.css -- copied, but is it used?
  • bootstrap.min.css -- missing! read from CDN.
  • bootstrap.bundle.min.js -- missing! read from CDN.
