I am new with D3, Javacript, and HTML.

The repository of my project is as follows:
Project:

• facebook_combined.txt
• index.html
• network.js

I am trying to access facebook_combined.txt from index.html to try to do a first visualization of it.
Here is the console when I execute the index.html

This is index.html
This is network.js

I have tried to reproduce other project online but I always get this error. My guess is that I am trying to access a local file from the server which doesn’t have access to it.
I didn’t find a way to run the html locally or to put the txt file online in a way that the server can reach it.
