How to make animation on canvas?

Question

JavaScript

It is required to implement sorting algorithm visualization like this https://www.cs.usfca.edu/~galles/visualization/Alg... .

I don't know what to start with. Google didn't turn up any results.
Maybe someone did something similar, let's see the source :)

Answer 1

Make a "record" of the sorting process using the command pattern gameprogrammingpatterns.com/command.html
put commands on the stack,
play commands by timeout , in
fact there will be something like
queue = [MoveCommand(1,3), MoveCommand(2,3), MoveCommand(3,1)]
and in the command already move the elements of the array, and start redrawing.
