Showing my cards; a few at least. Email me with any comments or questions.
I've added some of my better demos, prorotyping code snippets, and interaction designs over on my CodePen.io profile.
Standard underlines are boring, but serve their purpose well as the 'link' indicator on the web. I had seen a few sites and libraries attempt dressing up the standard underline, but none did it truly well... Meaning none were visually elegant, easy to edit for re-use, and easy for content editors to apply to their text content. My good friend Adam Luter was up to the challenge, and he deserves credit for helping to code and debug this idea.
What do you do when the guys paying your invoice are still stuck using IE7, but also need their data visualizations to work on their shiny new retina iPads? Image-based solutions provide great visual style, but lack ideal editability. Flash won't work for iOS, and similarly the HTML5 Canvas element won't work for most versions of IE. Mission not impossible, and probably simpler than you think.
Raphaël.js is awesomely useful in this for executing simple interactive charts that *could* otherwise be done using animation plug-ins like Flash, but now also need to work properly on iOS devices. The Raphaël library offers a single content-entry solution for ubiquitous support.
