There's suspicion, though, that the reason has more to do with Microsoft's internal politics, with the company wanting graphics and drawing in IE done using Silverlight instead.
SVG Web is more than an answer to Microsoft's foot-dragging, however. Google has declared for HTML 5 on the web, proclaiming last week that the web programming model has "won".
Support for graphics capabilities in HTML 5 should also be seen as Google's partial answer to Adobe Systems' Flash. Google has complained that Flash is not open source and its development is not driven by the community. Google said the benefit of SVG Web is that it would sit inside the DOM whereas Flash "sits on top of the web, it's not part of the web"
