clean + added svg lib

[L33TSP34KER]

ui_lib

This is a library designed to generate SVG on-the-fly or at runtime. Now, users can create dynamic SVGs using this library more easily and with greater flexibility. Here's an example usage:

But like Guillaume said, you can inject JavaScript, but this isn't a security flaw of the library; rather, it's related to Gnoweb.
because anyone can simply create an SVG with JavaScript and make an Realm, regardless of my library

example

func Render() string {
	canvas := svg.NewSvgCanvas(400, 200, "300,200,400,400", "", nil,
		svg.NewSvgCircle(100, 100, 50, "#FF0000", "", nil),
		svg.NewSvgRect(150, 150, 100, 80, 10, "#00FF00", "example-class", svg.NewSvgCircle(100, 100, 50, "#FF0000", "", nil)),
	)

	return canvas.Render()
}
