Wonderful summary and very well explained! Those graphics could be in a CS textbook :) A bit more (or perhaps another article) on how the tree can be encoded would be useful, since the total size of your compressed example would need to include the size of the tree. Also: JPEGs also have a Huffman tables region in their binary; haven't dug too deeply, but seems like they also use Huffman coding!
