Interesting data, but not the most readable.<p>Could you try:<p>- increasing contrast of text (vs background),
- making it horizontal (time is already there, no need to make the whole plot diagonal)
- making different author of language different color or font size than language (and perhaps, bottom to language name).<p>I believe it would add to readability.
Btw - the data is from wikipedia - <a href="http://en.wikipedia.org/wiki/Timeline_of_programming_languages-" rel="nofollow">http://en.wikipedia.org/wiki/Timeline_of_programming_languag...</a> if this is incomplete, then feel free to add the missing ones to the list give me a pull-request for this file - <a href="https://github.com/eiriklv/eiriklv.github.io/blob/master/timeline/programming-languages/js/data.js" rel="nofollow">https://github.com/eiriklv/eiriklv.github.io/blob/master/tim...</a>
This is one of those sites I wouldn't mind the site hijacking my scroll.
It would also be nice if you could show many any languages were created for a year in the year bar above, maybe on hover or as a badge.
