We all know some of the top websites on the web, such as Google, Yahoo, Twitter, Facebook etc. However, instead of seeing the most trafficked websites in a list format, nmap.org has compiled the top sites on the web in a visual format. Specifically, they have taken Alexa data, found the most popular sites, and then grabbed the icons off those sites. Finally, they created an image map of these icons, with icon size representing the total reach of that website. Check out the image below.
