Typeerror: Undefined Is Not An Object (evaluating 'm.layout.force')

I'm new to JSNetworkX. I created a graph using the examples from jsnetworkx.org but I can only log it, I can't display it. So this is index.html file: &

Solution 1:

The problem was including the latest version of D3.js.

Changing

<script src="https://d3js.org/d3.v4.js"></script>

to

<script src="https://d3js.org/d3.v3.js"></script>

will fix it.
