Uploading graphics from Word 2007 directly to my blog

Carrying on the experiments. How well does Word render native objects to blog posts? Here are some Word charts and graphics. The images you see have been rendered by Word and then uploaded. I’ve not edited or altered them in any way: what you see is exactly as it was uploaded. Fairly reasonable results I’d say. Of course, SVG would be nicer but maybe one day : -~)
