I am aware that it's possible to include Google's Visualizations in a post by publishing the chart/gadget in Google Docs (http://en.support.wordpress.com/google-docs/), but I'm not sure how to control the size of these charts etc. once included in a post.
Here (http://dl.dropbox.com/u/1058849/test_weight.html) I've got three simple Google linecharts that connect to dummy data in a Google Spreadsheet. Is it possible for me to present these charts similarly in a post/page/sidebar? I would prefer not to use a static image, as the data will be updated regularly, and I like having the tooltips. Alternatively, are there any similar visualization options for which wordpress.com shortcodes exist?
(Also, where would I find a markup reference for these forums?)
