D3js: how to generate standalone SVG files? (Nodejs)

Answer 1

I recently wanted to do just that and asked a question here. I was pointed to phantomJS. Using PhantomJS, I created a JS -

svggen.js:

var page = require('webpage').create(),
    url = 'http://www.example.com/wordcloud.html';

page.open(url, function (status) {
    if (status !== 'success') {
        console.log('Unable to access network');
    } else {
        var svgData = page.evaluate(function(s){
                var serializer = new XMLSerializer();
                var element = document.getElementById("svg1");
                return serializer.serializeToString(element);
        });
        console.log(""+svgData);
    }
    phantom.exit();
});

wordcloud.html:

Then I run

phantomjs svggen.js > svgFile.svg

The resulting svgFile.svg is a standalone SVG File. For d3cloud check this.
