<p>A sample showing how to use DOM nodes in a graph. Note that IE does not
support this technique.

<script id="js">
// Create a new directed graph
var g = new dagreD3.graphlib.Graph().setGraph({});
g.setNode("root", {
label: function() {
var table = document.createElement("table"),
tr = d3.select(table).append("tr");
tr.append("td").text("A");
tr.append("td").text("B");

g.setEdge("root", "B", {});
// Create the renderer
var render = new dagreD3.render();
// Set up an SVG group so that we can translate the final graph.
var svg = d3.select('svg'),
svgGroup = svg.append('g');
// Run the renderer. This is what draws the final graph.
render(svgGroup, g);
// Center the graph
var xCenterOffset = (svg.attr('width') - g.graph().width) / 2;
svgGroup.attr('transform', 'translate(' + xCenterOffset + ', 20)');
svg.attr('height', g.graph().height + 40);
