3/// The viewBox attribute defines the position and dimension, in user space, of an SVG viewport.
4///
5/// The value of the viewBox attribute is a list of four numbers: min-x, min-y, width and height.
6/// The numbers, which are separated by whitespace and/or a comma, specify a rectangle in user space
7/// which is mapped to the bounds of the viewport established for the associated SVG element
8/// (not the browser viewport).
9///
10/// A viewBox can be constructed out of a tuple:
11/// ```rust
12/// let view_box: svgplot::ViewBox = (1, 2, 3, 4).into();
13/// assert_eq!(view_box.min_x, 1);
14/// assert_eq!(view_box.min_y, 2);
15/// assert_eq!(view_box.width, 3);
16/// assert_eq!(view_box.height, 4);
17/// ```
