this causes the issue .enter().append("svg")

var svg = d3.select("#tree").selectAll("svg")
.data(d3.entries(orientations))
.enter().append("svg")
.attr("width", width + margin.left + margin.right)
.attr("height", height + margin.top + margin.bottom)
.call(d3.behavior.zoom().on("zoom", zoom))
.append("g")
.attr("transform", "translate(" + margin.left + "," + margin.top + ")");

Aight is only a shim for HTML, and doesn't provide SVG support. If you're looking to produce SVG with d3 in IE8, check out r2d3.
