Network.set_options doesn't work when loading the graph from a DOT file.

I tried using the set_options method as boludo00 demonstrated. This works fine.

However when I read the edges and nodes from a DOT file the options I set afterwards with set_options have no effect.

What you can do to replicate this:

import pyvis
graph = pyvis.network.Network()
graph.from_DOT("./example_dotfile.dot")
graph.set_options("""
var options = {
    "physics": {
        "enabled": false,
        "stabilization": 10,
        "barnesHut": {
            "springLength": 200
        }
    }
}
""")
graph.show("test.html")

Here is an example DOT file for testing:

digraph {
    a [label=12];
    b [label=7];
    c [label=3];
    a -> b[label="solid edge"];                     
    a -> b [label="dashed edge"]; 
    a -> c [label="dashed edge"]; 
    a -> c [label="dotted edge"];      
}

Adding the following to the generated js will work though.

options.physics = {
    enabled: false,
    stabilization: 10,
    barnesHut: {
        springLength: 200
    }
}

Here is the fix:

pyvis/pyvis/templates/template.html

Lines 165 to 168 in b11d105

	var options = parsedData.options;
	options.nodes = {
	shape: "dot"
	}

Change those lines to:

var options = parsedData.options;
options = Object.assign(options, {
    nodes: {
        shape: "dot"
    },
});
{% if options %}
options = Object.assign(options, {{options|safe}})
{% endif %}

I can confirm this works! :)

@Darkproduct Can you write a pull request for this change?

[Darkproduct]

Yea, I can do that. Should this also include the fix for #128? I mean the version of vis-network this project currently uses is 5? years old.

[jhunpingco]

Please. That makes sense.
