How to do thIs diagram with force-directed graph in D3.js?

Question

I made this diagram with viz.js.

The Dot code is very simple:

<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>

But the viz.js library is 2.3 MB! That is too large.

Is it possible to do the same with something like a force-directed graph in D3.js?

Answer 1

Eventually I decided to write the charting code myself, because jsPlumb conflicted in some areas with the jQuery Mobile js and css. It is not hard to do your own drawing on a html5 canvas and you end up with a 'lighter' app.

This the result:
