Multiple color interpolation

Pen

var color = d3.interpolateRgbBasis(["red", "yellow","green"]);

color(0) // red  - rgb(255, 0, 0)
color(0.5) // yellow - rgb(213, 191, 0)
color(1) // green - rgb(0, 128, 0)
color(0.25) // something between red and yellow -  orange - rgb(250, 120, 0)
color(0.75) // something between yellow and green -  rgb(122, 184, 0)

Positioning

fiddle - check legends positions

Adjusting legend positions horizontally

 var startX = 0;
 wrappers.each(function (d, i, arr) {
      var wrapper = d3.select(this);
      var text = wrapper.select('text');
      var bbox = text.node().getBBox();
      wrapper.attr('transform', 'translate(' + startX + ',-30)');
      startX += bbox.width + 35;
})

getting translation values from string

function getTransformation(transform) {
  // Create a dummy g for calculation purposes only. This will never
  // be appended to the DOM and will be discarded once this function 
  // returns.
  var g = document.createElementNS("http://www.w3.org/2000/svg", "g");
  
  // Set the transform attribute to the provided string value.
  g.setAttributeNS(null, "transform", transform);
  
  // consolidate the SVGTransformList containing all transformations
  // to a single SVGTransform of type SVG_TRANSFORM_MATRIX and get
  // its SVGMatrix. 
  var matrix = g.transform.baseVal.consolidate().matrix;
  
  // Below calculations are taken and adapted from the private function
  // transform/decompose.js of D3's module d3-interpolate.
  var {a, b, c, d, e, f} = matrix;   // ES6, if this doesn't work, use below assignment
  // var a=matrix.a, b=matrix.b, c=matrix.c, d=matrix.d, e=matrix.e, f=matrix.f; // ES5
  var scaleX, scaleY, skewX;
  if (scaleX = Math.sqrt(a * a + b * b)) a /= scaleX, b /= scaleX;
  if (skewX = a * c + b * d) c -= a * skewX, d -= b * skewX;
  if (scaleY = Math.sqrt(c * c + d * d)) c /= scaleY, d /= scaleY, skewX /= scaleY;
  if (a * d < b * c) a = -a, b = -b, skewX = -skewX, scaleX = -scaleX;
  return {
    translateX: e,
    translateY: f,
    rotate: Math.atan2(b, a) * 180 / Math.PI,
    skewX: Math.atan(skewX) * 180 / Math.PI,
    scaleX: scaleX,
    scaleY: scaleY
  };
}

// returns    {"translateX":20,"translateY":30,"rotate":0,"skewX":0,"scaleX":1,"scaleY":1}
console.log(getTransformation("translate(20,30)"));  

//returns {"translateX":-20.875265509281956,"translateY":78.11968385683471,"rotate":45,"skewX":20.000000000000004,"scaleX":1,"scaleY":1}
