The Rickshaw page is working fine for me in Chrome Canary (currently at Chrome 25) and Chrome 23, there's a single JS error but it's not preventing the examples from loading. Are you sure something else isn't the problem?
I checked Canary - the charts look fine, there is only a single js error in console. In Beta though, there is a lot of errors in d3.v2.js and rickshaw.min.js + that one that is reported in Canary (absinthe.min.js)
