SWFObject, the library that FusionCharts.js is built from, has version detection built into it.
I took some time today and hacked version detection from the newest version of SWFObject into FusionCharts.js and attached the result to this post.
I set the version requirement to at least 8.0.0 ... I have no idea if that is the minimum version or not
It seems to work for me, but it would be much better if the FusionCharts team would integrate the lastest SWFObject into FusionCharts.js completely.
