I opened tutorial from d3 site http://mbostock.github.com/d3/tutorial/bar-2.html in IE8 and fail => http://i.imgur.com/VPixH.png
Later, I tried to run other examples and the same errors. Is it known issue?
IE8 and below are not supported; they don't support SVG and many other web standards. If you want to use IE8, you'll need to use Chrome Frame.
