How to fix the PyVis Knowledge Graph error: localhost refused to connect

If you’re trying to build a knowledge graph, you might be using PyVis, which is a fast way to generate visual network graphs using Python. You can use PyVis in Jupyter Notebooks, locally, or in my case, generate the graphs as HTML files and then visualize those.

❌ The Problem

If you’re trying to run your code, you might run into a number of issues, such as localhost refused to connect like what is shown below:

      PyVis: localhost refused to connect error
   

✅ The Solution

By importing and leveraging the HTML and display modules from IPython.core, we can then add this extra line to display the knowledge graph with: display(HTML(filename='example.html'))

Check out the code and the output below:
