/*!
The drawing utils for Plotter. Which handles the both low-level and high-level
drawing.
For the low-level drawing abstraction, the module defines the `DrawingBackend` trait,
which handles low-level drawing of different shapes, such as, pixels, lines, rectangles, etc.
On the top of drawing backend, one or more drawing area can be defined and different coordinate
system can be applied to the drawing areas. And the drawing area implement the high-level drawing
interface, which draws an element.
Currently we have following backend implemented:
- `BitMapBackend`: The backend that creates bitmap, this is based on `image` crate
- `SVGBackend`: The backend that creates SVG image, based on `svg` crate.
- `PistonBackend`: The backend that uses Piston Window for real time rendering. Disabled by default, use feature `piston` to turn on.
- `CanvasBackend`: The backend that operates HTML5 Canvas, this is available when `Plotters` is targeting WASM.
