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()
}

I think your implementation is not very easy to use,
And what you're doing is illegal from the svg spec 😄
You should not use rectangles as containers for children shapes.
Only some elements can be containers: g, svg, etc.. see https://www.w3.org/TR/SVG/struct.html#TermContainerElement

Did you make your package because something was wrong with p/demo/svg ?

By reviewing gnomod.toml I also see that package and folder name differs (ui_lib vs svg)

I would also add these standard primitives as they're often used: line, polygon, path

And also some example and test file would be nice !

After thinking about all of this I'd prefer to use something like this :

func Render() string {
    return svg.Canvas().
        Size(400, 200).
        ViewBox("300,200,400,400").
        Add(svg.Circle().At(100, 100).Radius(50).Color("#FF0000")).
        Add(svg.Rect().At(150, 150).Size(100, 80).Rounded(10).Color("#00FF00").Class("example-class")).
        Add(svg.Circle().At(100, 100).Radius(50).Color("#FF0000")).
        Render()
}

If you want grouping, you should be able to do it with official p/demo/svg lib like this:

func Render() string {
      canvas := svg.Canvas{Width: 400, Height: 200, ViewBox: "300 200 400 400"}
      group := svg.Group{Attr: svg.BaseAttrs{Class: "example-class"}}
      group.Append(
          svg.Rectangle{X: 150, Y: 150, Width: 100, Height: 80, RX: 10, RY: 10, Fill: "#00FF00"},
          svg.Circle{CX: 100, CY: 100, R: 50, Fill: "#FF0000"},
      )
      canvas.Append(
          svg.Circle{CX: 100, CY: 100, R: 50, Fill: "#FF0000"},
          group,
      )
     return canvas.String()
}
