おれの考えた最強のD3.jsフレームワーク

gistfile1.js

function nop() {
  "use strict";
}

module.exports = function createComponent(options) {
  "use strict";
  var enter = options.enter || nop,
      exit = options.exit || nop,
      update = options.update || nop;

  return function(root) {
    root.each(function(data) {
      var selection = d3.select(this).data(data);

      selection
        .enter()
        .call(enter);

      selection
        .exit()
        .call(exit);

      root
        .call(update);
