The Canvas widget provides structured graphics facilities for Tkinter. This is a highly versatile widget which can be used to draw graphs and plots, create graphics editors, and implement various kinds of custom widgets.

The canvas is a general purpose widget, which is typically used to display and edit graphs and other drawings.

Another common use for this widget is to implement various kinds of custom widgets. For example, you can use a canvas as a completion bar, by drawing and updating a rectangle on the canvas.

The Canvas is the only scrollable widget in Tkinter. This is useful for more complicated GUIs where there may not be enough space for all the widgets.
