Description: Downloadable Java visualization of encoding using a Huffman tree. It's unclear how the Huffman tree itself is generated, and the program's stepwise operation does not show walking down through the tree to encode a letter.
Evaluation: Strengths: no code or algorithm shown; allows arbitrary strings. Weaknesses: difficult to follow; unclear what exactly is being demonstrated; continuous operation simply runs to the end without showing each step at a speed humans can understand
