Design for an interactive webpage that will be built using JavaScript

We're looking for a designer to help us create an interactive web page. It would have clickable bits that slide out to reveal more information. We would provide all of the content; we just need someone who could design it in a visually appealing way so that it would be buildable in Javascript and implemented into a page on our blog.

An example of the kind of usability we're looking for is this: http://inequality.is/fixable. Where you click on an item and more information is revealed about it. However, it would have a less complex design, with only a couple of colours like this: https://informationisbeautiful.net/visualizations/common-mythconceptions/

Please provide examples of other similar apps/pages/graphics that you've designed.
