I've been working on rewriting my Wordpress SVG inlay plugin as a Drupal module. So far it works pretty well but I'm not ready to say it's secure or functional for most sites. The basic concept of the SVG inlay is that sometimes you just want to display an SVG image in a post or page. Not as a style element but as something that visitors want to look at which is relevant to the content. Like a chart, a graph, a network diagram, maybe even a little game.
Jeff just put up some web stats made pretty by graphs done with SVG. He's also got a way of embedding SVG into an HTML page that shows up in most browsers. For many browsers an object element is enough but Internet Explorer with Adobe SVG Viewer 3 requires an embed tag to work properly. I think that's the gist of it. Jeff's got a good snippet of code to handle this, but it's kind of ugly and not convenient to use in a blog post.
