The <svg> element is a container that defines a new coordinate system and viewport.
It is typically used as the outermost element of SVG documents, but can also be nested to create local coordinate systems.
Viewport and ViewBox: Why they matter
One of the most powerful features of SVG is the ability to separate the drawing coordinates from the display size.
- Viewport (
width/height): This defines how much space the SVG occupies in the browser or parent element. Think of this as the "frame" of the window. view_box: This defines the internal "world" of your drawing. By setting aview_box, you can define a stable coordinate system (e.g., 0 to 100) and your drawing will automatically scale to fit whateverwidthandheightyou later choose for the viewport.
If you don't set a view_box, the coordinates you use in your shapes will
be interpreted as "user units", which usually map 1-to-1 to pixels.
Attributes
x,y- Position of the SVG container. Use these when nesting an SVG inside another to shift the entire sub-drawing.width,height- Display size. Use these to control the physical size on the screen. Values can be numbers (pixels) or percentages.view_box- The internal coordinate system. Essential for making your graphics responsive and independent of their display size.preserve_aspect_ratio- Controls what happens when theview_boxand viewport have different shapes (e.g., a square drawing in a wide frame).
Examples
# This creates a responsive circle that always stays centered,
# no matter what size the SVG is scaled to.
Vectored.Elements.Svg.new("100%", "100%")
|> Vectored.Elements.Svg.with_view_box(0, 0, 100, 100)
|> Vectored.Elements.Svg.append(Vectored.Elements.Circle.new(50, 50, 40))
Summary
Functions

Functions
Append children to the SVG element.
Accepts a single element, a list of elements, or a function that returns elements.
Append elements to the <defs> section of the SVG.
If no <defs> element exists, one will be created.
Set the x and y coordinates of the SVG container.
Note: This generally only has an effect when the SVG is nested inside another SVG.
Remove a dataset attribute
Remove private metadata.
@spec new() :: t()
Create a new SVG document container.
Create a new SVG document with specified dimensions.
Examples
Vectored.Elements.Svg.new(100, 100)
Vectored.Elements.Svg.new("100%", "100%", [circle])
Set a dataset attribute. Mimics the DOM Element.dataset API. The key will be converted from camelCase to kebab-case for the data-* attribute.
Security
The key is converted to an atom at render time (required by :xmerl).
Never pass untrusted/user-derived strings as key — unbounded distinct
keys exhaust the atom table and crash the BEAM. Use static key names.
value is safe and may be dynamic.
Store private metadata in the SVG struct. This data is not rendered to SVG.
