Maybe this site should be designed better? Meaning it is not readable on mobile. It is not any better on the desktop. Also piecharts - really? Do they know that people with even minor color blidnes do not read piecharts in same way as you think? I 100% understand and agree with points but this site shows that achieving these points is really really hard. Maybe impossible?
