d3.select("#save").on("click", function(){   var html = d3.select("svg")         .attr("version", 1.1)         .attr("xmlns", "http://www.w3.org/2000/svg")         .node().parentnode.innerhtml;    //console.log(html);   var imgsrc = 'data:image/svg+xml;base64,'+ btoa(html);   var img = '<img src="'+imgsrc+'">';    d3.select("#svgdataurl").html(img);  });
