easy d3 zoom and pan

I know a lot of people have trouble zooming and panning d3. Indeed, I found myself in a situation where I had a simple bar chart to which I wanted to add the zoom behavior, and also make the full chart draggable. I saw several extremely complex examples of d3 charts with zooming and panning, and thought that there must be an easier way, particularly if you don't need to scale the x and y axes. There is, and here is is in CoffeeScript:

vis.call(d3.behavior.zoom()
  .on("zoom", ->
    g.attr("transform", "translate(" + d3.event.translate[0] + "," + d3.event.translate[1] + ") scale(" + d3.event.scale + ")")
  )
)

Here is about the simplest example I can think of that gets you a working skulpt environment. This little sample shows regular python as well as importing a module.

Getting the Alexa top 1 million sites directly from the server, unzipping it, parsing the csv and getting each line as an array.
var request = require('request');
var unzip = require('unzip');
var csv2 = require('csv2');
request.get('http://s3.amazonaws.com/alexa-static/top-1m.csv.zip')
.pipe(unzip.Parse())
.on('entry', function (entry) {
entry.pipe(csv2()).on('data', console.log);
})
