I really enjoyed this course because it was exactly what I was looking for. I wanted to learn more about what D3.js could do to visualise CSV based data and Bill did an excellent job of walking through the steps involved. Did I get every detail? No, but Bill gave me a skeleton from which I can now build and I think he did an excellent job of this.

A great, well-paced introduction to D3!

The best and most concise D3 guide I’ve found on the internet 🙂
