Display Graphics #
Everything graphics in CircuitPython is built around the displayio library.
display graphics
First you need a display object, which is usually preconfigured for your board if it has a built in display, as board.display. It will automatically refresh the screen. The root of the screengraph should already be set to a group, so you can append to it.
display = board.display
display.root_group.append(some_gfx_object)
