This project was the one that made me truly learn the secrets of D3. From how domain and range work to ticks format, D3 time format, axis styling and even SVG tricks like inserting HTML directly into SVG. After completing this project I could have said that I had some clue what D3 is about. What I found out while working on this even tho it had nothing to do with data visualisation was that text displayed with a slight shadow sticks out more than without and also that pure black does not look the best on a white or white-ish background, so a slightly "lighter" black is better.
