I think that certain graphs have issues and some don't.
I've got graphs with pax load factors and route share, however none for route demand and supply ect. They are however lacking the labels that are provided in the current flash versions.
My guess would be that some are not working because they are multi stage graphs. Not only do you have Y, C & F on top of one another but you also have the supplied Y, C & F from your airline and the overall supplied capacity. So whilst they have developed javascript versions of the simpler charts, they have not done so for the more complicated ones.
