The website I'm building will have content in various languages. I'm looking for a nice way to present the "langages" data, for those interested.
I really like this visualisation : http://www.climateinstitute.org.au/lcci
It is basically a series of sparklines, drawn at decreasing heights. I would use it, for instance, to display the overall number of posts in a language (→ height of the sparkline), and the evolution of this number (→ the sparkline itself).
Is there a chart drawing library that could do something like that ? I don't need it to be "clickable" / zoomable, a static image would be fine.
