Question is:
How to display it in a list like this with bullet points:

Node Name : Test Name
Keywords List :

Untested as I can't see your full solution, but you should be able to build a basic list structure by looping through your array:

var keywordList = "<ul>";
for(var i = 0; i < d.keywords.length; i++){
  keywordList += "<li>" + d.keywords[i] + "</li>";
keywordList += "</ul>";

And then simply add the keywordList on the end when you set the HTML, instead of the d.keywords:

.html("Node name : " + d.NodeName + "<br>" + "Keywords list: " + keywordList)
