In case of a simple non-interactive images alt may suffice. However, SVG  
can be used for much more than that, e.g. infographics and charts, which  
contain text and data and may have buttons and other interactive elements.

Saying that <circle> is clickable would help, and would be improvement  
over just a circle drawn on canvas and hit-tested against mouse click with  
custom JS.
