Over the years, I've written a number of posts on this blog on the topic of binary data visualisation. I looked at using space-filling curves to understand the structure of binary data, I've showed how entropy visualisation lets you trivially pick out compressed and encrypted sections, and I've drawn pretty pictures of malware. Unfortunately the tools I wrote all produced static images, which made making practical use a pain. You really need interactivity to be able to combine visual exploration with inspection of the actual underlying data, and to let you easily export interesting sections.
