if you are needing to draw the text after the rect, like if the fill-opacity is 1.0, you can do this:

var svg = d3.select("body").append("svg:svg")
    .attr(...)

var layer1 = svg.append('g')  // draw in this order
var layer2 = svg.append('g')

var text = layer2.append("svg:text")      // create in this order
    .attr(.....)

var bbox = text.node().getBBox();

var rect = layer1.append("svg:rect")
    .attr(...)
    .attr("width", bbox.width)
    .attr("height", bbox.height)
