That is an excellent set of articles for learning d3! I love how it gives an overview of all the d3 modules, then explains them in groups by related functionality. I just started exploring, and will study it over time. Thank you for sharing your knowledge, the articles are really well-done and high quality. I'm guessing the visualization of d3 modules is done in d3 itself. Beautiful in concept and presentation.
