As an employee of a company that provides digital security through machine learning, Stephanie Yee spent a lot of time familiarizing clients with the secret sauce behind her product. So she and her colleague, designer Tony Chu, set out to create an interactive graphic that would do the explaining for them. The pair chose a topic they thought would be intuitive to most people--real estate prices--and created an interactive environment that builds in complexity as the user scrolls. In the first 30 days, the site got 250,000 page views worldwide. Feedback showed Chu and Yee that experts in many fields could use their interactives.
