Is there a way to save the rendered node locations obtained by the layout algorithm?

Question

When I open the saved HTML network file, it takes quite some time to load my network of a few thousand nodes. Would it be possible to save the node locations to avoid running the network layout algorithm whenever I open the file?

Answer 1

This is more of a manual solution, but it should work - it is about getting the node locations once they are loaded in your browser through javascript and then copy the locations to the html file.

See https://holzsec.github.io/rfcview/graphs/all_static.html

1. Render Graph in Browser => F12 Console

    network.storePositions();
    console.log(JSON.stringify(data.nodes.get()))

Copy output to clipboard

2. Edit html file/ cp html to version_static.html

• Comment out loadbar div
• Comment out loadbar js/css (optional)
• Set physics options to false

"physics": { "enabled": false, "repulsion": {

• goto nodes = and copy output from 1) to the vis.DataSet array

Save and done! (Happy to collaborate on some sort of automation for this)
