This is a simple d3.js graph used as an example in the book D3 Tips and Tricks.
It is aimed at providing some exposure to some d3.js functions and should be taken in context with the text of the book which can be downloaded for free from Leanpub.

I downloaded everything you have above but when I open index.html on Chrome or Internet Explorer, I just see a blank page.
armianhanelli, make sure that the data.csv file is linked correctly in your folder, something like( data/data.csv).
Hi, for those that have the empty page problem it might be because your internet browser, such as chrome, does not allow to use any files inside your hard disk.
You should just change the permits of your browser. FireFox has that option by default.
Thanks for the solution rafaellopezgarcia. It didn't work in Chrome or Edge but worked well in Firefox.
You should always use local web server to access files from your hard disk with the browser.
Detailed instructions: https://github.com/mrdoob/three.js/wiki/How-to-run-things-locally
Great example and tutorial! Thank you!
I fixed my empty page problem and shared my solution using a simple, local web server in python3 here: https://stackoverflow.com/questions/21006647/cannot-import-data-from-csv-file-in-d3/60383167#60383167

I tried to replicate this example but failed. I tried basically several examples. Here's my success and failure:
Success: Link1 Link2
Failure: Link3
[For Link3, I have kept us.json in my folder which is required. Still it didn't work]
