Okay, there are tons of sparkline libraries on the web (PHP, Python, Ruby, etc.) But it does not appear that anyone has implemented them within Cocoa on a Mac so the premiere content creation platform can easily generate these dense collections of information.
So, what would an extension on NSAttributedString look like so sparklines can be easily embedded in a standard text view?
For that matter, should there be a tagging system so data could be entered easily to render the sparkline?
Maybe a custom control that could be inlined in text?
The possibilities abound.
