[Tkinter-discuss] getting started - canvas - "multislider" / function editor

I'm new to GUI programming, & self taught at Python which is the only
"real world" programming language i know - I picked it up last year to
try and work with Csound to make "algorithmically assisted"
compositions, & now hopefully through tkinter some basic interfacing
options. (Csound is accesible via python through an api, &/or vice versa...)
What i want to do is use the Canvas object (assumedly with a series of
rectangles on it, let's say 64 or 128 or 256 being the likely number of
candidates depending on the editing task..) so that i can graphically
edit the contents of function tables in csound.
The rectangles on the canvas will simply be lenghtened or shortened in
the vertical direction, & all sit one next to the other (so it looks
like the interface from an EQ on a stereo, or a "skyline" type
appearance...maybe coloured rectangles will identify every 8 or 10 or 12
index values or something...
But i've got no experience of this, have run some very simple examples
illustrating some basic tkinter behaviour ("hello world" that type of
thing...) - but surely there is something around showing some simple
canvas operations so i can start hacking it & getting this started, &
learning something about tkinter in the process??
Does anyone know or have an implementation of this type of thing in
tkinter, or alternately some simple & pedagogically useful examples of
basic canvas & user interfacing types of operations? (resizing boxes on
a canvas with the mouse & reporting values being the general idea...)
