QUESTION
This same question was asked five years ago with no answer, maybe since then there's a solution. I don't understand how formatting works in Sigma.js.
Maybe sigma isn't the right tool for the job? I thought I'd be able to accomplish something like this (except maybe a little prettier than my MS paint sketch):
But Simga doesn't seem to want to be anchored like I imagined. For example, with the example code on the library's website:

QUESTION
Am completely new to flask so pls forgive me if dumb question
I'm learning how to use flask and want display graphs generated by sigma.js.
When I open "svg-freestyle-renderer.html" directly by double-clicking on the file, it opens up and shows an interactable network graph with nodes and connections.
Now I want to view the same graph by accessing the html in a flask server but when I open the page, it only loads the background colour without the graph. I've triple checked all my files are in the right directory.
Is there a difference between opening a html file directly and accessing it through flask that I'm missing?
This is how I'm calling the html in my py file:

Failed to load resource: the server responded with a status of 404 (NOT FOUND)
for all your files.
Put your js files in a directory named static or you can specify your own creating your app app = Flask(static_folder="src")
And in your templates use {{ url_for('static', filename='sigma.core.js') }} to access your js-files. You won't be able to open this page in browser directly from filesystem, but will it perfectly served by app.
Links about static files and app API for reference.
