[anti-pattern]

Actually, the entire reason I made this site was because I thought the way MacRumors visualized the data wasn't very good. If they had done a better job, I wouldn't have needed to make this.

As for credit... what should I be crediting them for? I'm just collecting a list of dates and then visualizing the data.

A simple link at the bottom saying, "inspired by macrumors.com buyers guide" would go a long way towards giving credit to the original concept. You can even even embed the url, so it's just a small font, "inspired by" to keep the page clean.
