Quiero correr D3 de un CakeFile

Question

Me gustaría ejecutar un código D3 de la línea de comandos.Inicialmente, acabo de intentar algo como:

task 'data', 'Build some data with d3', ->
      d3 = require('lib/d3.v2')
      console.log "d3 version = "+ d3.version

Pero esto no funcionó.Tengo errores como este:

node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
          ^
ReferenceError: CSSStyleDeclaration is not defined
    at /Users/mydir/Documents/classes/middleclass/app/lib/d3.min.js:1:21272
    at Object.<anonymous> (/Users/mydir/Documents/classes/middleclass/app/lib/d3.min.js:2:25395)
    at Module._compile (module.js:432:26)
    at Object..js (module.js:450:10)
    at Module.load (module.js:351:31)
    at Function._load (module.js:310:12)
    at Module.require (module.js:357:17)
    at require (module.js:368:17)

    at /usr/local/lib/node_modules/coffee-script/lib/coffee-script/cake.js:39:26

Entonces ... Pensé que esta excepción me estaba diciendo que necesito ejecutar D3 dentro de un navegador.Probé esto de diferentes maneras de pareja.Básicamente, sin embargo, pensé que si acababa de despedir a Phantomjs, probablemente podría hacer lo que quería hacer.Aquí estaba mi CakeFile:

task 'data2', 'Build some data with d3', ->
  hem = spawn 'hem', ['server']
  phantom = require('phantom')
  phantom.create (ph) ->
    ph.createPage (page) ->
      page.open 'http://localhost:9294/sandbox.html', (status) ->
        page.evaluate (-> window), (window) ->
          require = window.require
          require('lib/d3.v2')
          console.log("d3 version = "+ d3.version)
          ph.exit()
          hem.kill()

Cuando voy a esta ruta, sin embargo, siempre termino recibiendo excepciones como esta:

TypeError: object is not a function
    at Object.CALL_NON_FUNCTION (native)
    at Object.<anonymous> (/Users/mydir/Documents/classes/middleclass/Cakefile:52:13)

    at EventEmitter.<anonymous> (/Users/mydir/Documents/classes/middleclass/node_modules/phantom/node_modules/dnode/node_modules/lazy/lazy.js:46:39)

¿Qué estoy haciendo mal?

Gracias a MBostock, obtuve el siguiente trabajo:

mi paquete.json:

{
    "name": "app",
    "version": "0.0.1",
    "dependencies": {
        "d3": "~2.8.0",
        "jsdom": "~0.2.13"
    }
}

MI CAKEFILE:

task 'd3', 'Do something with d3', ->
  jsdom = require('jsdom')
  jsdom.env({
    html: 'public/sandbox.html'
    done: (errors,window) ->
      require('d3/index.js')
      console.log("d3 version = "+ d3.version)
  })

See D3's package.json. More specifically, the file you want to require when running inside Node or similar environments is index.js rather than d3.v2.js; this file contains some special patches that make D3 compatible with the require operator.

To try it out for yourself, cd to the d3 repository, run node to create an interactive shell, and then say

var d3 = require("./");

Or, if you're in your own project folder, if you've installed D3 into node_modules/d3 via npm (npm install d3), you can say:

var d3 = require("d3");
