Where SVG comes from
The W3C published SVG 1.0 as a Recommendation in September 2001 after merging competing vector proposals (Adobe's PGML and Microsoft's VML), with SVG 1.1 following in 2003. Browser support matured slowly — full inline HTML5 embedding only became universal in the early 2010s — while the SVG 2 specification has remained a long-running work in progress.
