如何在D3.js中使用力导向图来制作图表？

Question

我用viz.js制作了这个图。

Dot代码非常简单：

<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>

但是viz.js库是2.3 MB！那太大了。

是否可以对D3.js中的强制导向图做同样的事情？

最终我决定自己编写图表代码，因为jsPlumb在某些方面与jQuery Mobile js和css发生冲突。在html5画布上绘制自己的绘图并不难，最终会得到一个“更轻”的应用程序。

结果如下：
