When I noticed that both have an arc method that gave me pause.
Apparently, PIL provides IP (image processing: ...while Tkinter provides widgets. In PIL, arc allows one to draw on images but doesn't allow one to display them. The display and presentation is the function of Tkinter, and can draw on the widget canvas where an image, from PIL, might be placed. Comments?
Yes you have understood pretty well. PIL provides more sophisticated IP than Tkinter can do on its own. For simple images such as charts/graphs you might decide to draw them direct in Tkinter without using PIL. For that reason Tkinter canvas allows you to draw shapes, such as arc, directly on the canvas. For more sophisticated use (such as complex charts) you might use a plotting library to create the image and then display the image in Tkinter. Or to manipulate sophisticated graphics (like photos) you would probably use PIL or ImageMagik or somesuch.
