Here is what I found… if you know of any JS SVG API I have not mentioned please, please let me know.
dojox.gfx (GFX) is a cross-platform vector graphics API. It loosely follows SVG as the underlying model. GFX helps to isolate your application from the many native vector graphics implementation differences across all modern Browsers.
Modern browsers like Firefox, Safari, Chrome and Opera support the HTML5 canvas tag to allow 2D command-based drawing. ExplorerCanvas brings the same functionality to Internet Explorer. To use, web developers only need to include a single script tag in their existing web pages.
- jQuery SVG
A jQuery plugin that lets you interact with an SVG canvas.
