Intention

When I see the title "lying with data", I immediately think of the sales advertisements companies make to attract customers. Usually they lie with the discount of products to make customers feel like they just have to buy something because the discount is huge. However, customers now are aware of the lies of sales. Most of them know that a "up to 70%  sale" does not necessarily mean every item they but is 70% off. Therefore I want to show my data in a way that convince customers that their is in fact, a 70% off and sometimes even more than 70%.
