Exploring the world of d3 network visuals, I stumbled upon a fascinating example on this link. The visualization showcases relationships between various groups using different colors. Now, my curiosity leads me to wonder if I can customize the link colors based on these groups. Is it possible to achieve this by tweaking the JavaScript code provided in the link?
Looking forward to your insights and answer. Thank you in advance!

Key modifications:
1) The color of the line is determined by the group of source and target nodes. To ensure they belong to the same group, check if
graphs.nodes[d.source].group === graphs.nodes[d.target].groupd.source.group and d.target.group. If both groups are the same, the line's stroke matches the color of the nodes.
2) Links between nodes in different groups receive a grey stroke through the addition of a specific class.
.attr('stroke', function (d) {
if (d.source.group === d.target.group) {
return color(d.source.group);
} else {
d3.select(this).classed('different-groups', true);
}
})
CSS style:
.different-groups {
stroke: #999;
}
