ecently, I ran into this remarkably versatile tool called d3.js, which is intended to assist JavaScript programmers to visualize various forms of data.One of the first things I did was to look for any tutorial videos on YouTube, and did I find a treasure trove of d3.js video tutorials! User d3Vienno has around 20 tutorials, many of them in the 10-minute duration, and very easy to follow. (The only thing unusual in the d3Vienno's videos is the narrator's pronunciation of the vowel sound in DOM (Document Object Model) with a \ü\, rather than with a \ä\).
