The number of documents found from Google keyword search can not tell everything about the trend, however, I believe, it says something if we compare it over a certain time span. The search result may have some flaws like the keyword "java" includes Java island or "Pascal" gets some help from the mathematician Pascal and so on. Also, we may have to consider the net increase of the web pages during the 5 year span. But the comparison still stands if we look at it in relative terms.

Anyway, it an interesting snapshot.

SVG is a family of specifications of an XML-based file format  for describing 2D vector graphics, both static and dynamic. Though there have been several tries to make it 3D, SVG has no 3D support. All major modern web browsers except Microsoft Internet Explorer support and render SVG markup directly. To view SVG files in Internet Explorer, either users have to download and install a browser plugin, such as Adobe SVG Viewer from Adobe SVG Viewer.

Here is an example of SVG animation
