I have some ideas I would like to experiment with relating to data compression, but am finding it difficult to decipher some parts of how the standard are applied "in real life". I would like to look at some sample compressed files to observe how the the blocks are arranged and the huffman tree(s) are structured.
Are there any tools in existence which can help visualize this for a given compressed file (zip/gzip/deflate etc)? I'm picturing something like a tree view or some form of graph visualizer.
