D3.js에서 힘 지향 그래프로 다이어그램을 만드는 방법은 무엇입니까?

이 다이어그램을 viz.js로 만들었습니다.D3.js에서 힘 지향 그래프로 다이어그램을 만드는 방법은 무엇입니까?

<script type="text/vnd.graphviz" id="myDiagram"> 
digraph G { 
graph [ 
    fontname = "Arial", 
    fontsize = 18, 
    label = "Digest Email Flow Chart", 
    size = "4,4" ]; 

node [ 
    shape = ellipse, 
    sides = 4, 
    distortion = "0.0", 
    orientation = "0.0", 
    skew = "0.0", 
    bgcolor = lightgray, 
    style = filled, 
    fontname = "Arial" ]; 

"Email Notification" [shape=ellipse, shape = "Mrecord" label="Digest Email\n(scheduled)"]; 
"Sentiment Analysis" [shape=ellipse, shape = "Mrecord" label="Sentiment Analysis\n(triggered)"]; 
"Google News"   [shape=ellipse, shape = "Mrecord" label="Google News\n(scheduled)"]; 
"Dilbert Daily Comics" [shape=ellipse, shape = "Mrecord" label="Dilbert Daily Comics\n(scheduled)"]; 
"Time Series Chart" [shape=ellipse, shape = "Mrecord" label="Time Series Chart\n(triggered)"]; 
"Twitter Stream"  [shape=ellipse, shape = "Mrecord" label="Twitter Stream\n(scheduled)"]; 

"Email Notification" -> "Time Series Chart" [dir = "back"]; 
"Email Notification" -> "Dilbert Daily Comics" [dir = "back"]; 
"Time Series Chart" -> "Twitter Stream" [dir = "back"]; 
"Sentiment Analysis" -> "Google News" [dir = "back"]; 
"Email Notification" -> "Sentiment Analysis" [dir = "back"]; 
} 
</script>
