Me gustaría ejecutar un código d3 desde la línea de comando. Inicialmente intenté 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 /usr/local/lib/node_modules/coffee-script/lib/coffee-script/cake.js:39:26

Entonces ... pensé que esta excepción me decía que tenía que ejecutar d3 dentro de un navegador. Intenté esto de diferentes maneras. Básicamente, sin embargo, pensé que si solo encendía fantasmas probablemente sería capaz de 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 sigo esta ruta, siempre obtengo excepciones como esta:

¿Qué estoy haciendo mal?

Gracias a mbostock Tengo el siguiente trabajo:

My package.json:

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

My 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)
  })
