"""Create a SVG from a :py:class:`VectorData` instance.
If no page format is provided (or (0, 0) is passed), the SVG generated has bounds tightly
fitted around the geometries. Otherwise the provided size (in pixel) is used.
By default, no translation is applied on the geometry. If `center=True`, geometries are
moved to the center of the page.
No scaling or rotation is applied to geometries.
Layers are named after `layer_label_format`, which may contain a C-style format specifier
such as `%d` which will be replaced by the layer number.
If `single_path=True`, a single compound path is written per layer. Otherwise, each path
is exported individually.
For previsualisation purposes, pen-up trajectories can be added to the SVG and path can
be colored individually (``color_mode="path"``) or layer-by-layer (``color_mode="layer"``).
Args:
output: text-mode IO stream where SVG code will be written
vector_data: geometries to be written
page_format: page (width, height) tuple in pixel, or (0, 0) for tight fit
center: center geometries on page before export
source_string: value of the `source` metadata
single_path: export geometries as a single compound path instead of multiple
individual paths
layer_label_format: format string for layer label naming
show_pen_up: add paths for the pen-up trajectories

If no page size is provided (or (0, 0) is passed), the SVG generated has bounds tightly
fitted around the geometries. Otherwise the provided size (in pixel) is used. The width
and height is capped to a minimum of 1 pixel.
By default, no translation is applied on the geometry. If `center=True`, geometries are
moved to the center of the page.
No scaling or rotation is applied to geometries.
Layers are named after `layer_label_format`, which may contain a C-style format specifier
such as `%d` which will be replaced by the layer number.
For previsualisation purposes, pen-up trajectories can be added to the SVG and path can
be colored individually (``color_mode="path"``) or layer-by-layer (``color_mode="layer"``).
Args:
output: text-mode IO stream where SVG code will be written
document: geometries to be written
page_size: if provided, overrides document.page_size
