I have improved my D3.js experience dramatically over the past two years.I have lived several drastical improvements on my way of creating D3.js charts during the last 2 years. Usually when I have increased my skill level in D3 itthey coincided with reading someany of the books I introduce in this post. The examples, tutorials and blog posts below should be helpful for wherever you are you on own your D3 journey., but I think they could also be reached through different ways, including the following examples, tutorials and blog posts.

Assessing your own level

Firstly I willI would like to define four Dd3.js levels of experience in a broad sense:

• Complete Beginner: You don't hold any previous experience with D3.js or any front- end technologiesy like HTML or CSS.
• Basic: You have some HTML/CSS/JavaScript skills and havehaving playeding with some D3.js examples, but you don’tnot completely understanding allsome of the patterns and mechanics that it uses.
• Intermediate: You already know how to customize D3.js graphs given existing examples you find in the wildsearch engines, but you struggle to reuse them and you aren’t quite happy with the quality of the code itself.
• Proficient: You’ have already built a lot of different D3.js graphs, tested and integrated them with different technologies or libraries and you even created packages to easily share logic between projects.

Complete Beginner

Books

Scott Murray’s Interactive Data Visualization for the Web. You can read it for free online O'Reilly and it covers much of the basics needed for building your first interactive graphs.

Tutorials and hHand’s- on ‘Learning

• Scott Murray’s D3 Tutorials. The seed material of his O’Reilly book.
• The DashingD3js.com free tutorial is a very complete guideand,.
• Tto play around and experiment,, the Codecademy D3 tutorial is a good place to start.should work fine.

Reference links

Check what you can do with Christophe Viau’s D3.js Gallery, it is a pretty extensive list of charts made on D3 and sorted by graph type (bars, pie, bubbles and so on).
