spacecurve

It looks like we've traveled a similar path. The precursor to binvis is scurve, a (slow, dodgy) command-line tool to do basically what dump2png does: https://github.com/cortesi/scurve I have a blazing fast command-line version of binvis in Rust that I plan to release in the next month or so. I really need make some time to turn back to this.

Right - these are the frequency dot plots I first saw in Greg Conti's work (some examples here: http://sebug.net/paper/Meeting-Documents/BlackHat-USA2008/BH...). They're definitely on the way. Regarding other space-filling curves - I'm in two minds about this. I've implemented z-order and the H-curve for binvis, but for different reasons neither of these are as useful as the Hilbert curve, so they're not exposed in the interface. My feeling now is that I should pick one locality preserving layout and one intuitive layout to keep things simple and usable. I want binvis to be a workaday tool, so I'm keeping my space-filling curve geekery to another project (https://github.com/cortesi/scurve).

I'm somewhat late to the party, but I spent some time playing with procedural colour picking using space-filling curves (the Hilbert curve in particular). I describe the basic technique here: http://corte.si/posts/code/hilbert/portrait/index.html And you can see what this looks like when used to visualize sorting algorithms at large scale here: http://corte.si/posts/code/sortvis-fruitsalad/index.html And here: http://sortvis.org/ I've also published an Open Source project that might be useful to anyone who wants to play with these ideas: https://github.com/cortesi/scurve There are some limitations to the process as described - most obviously the fact that I'm using the RGB color space which is not the best match for human color perception. RGB is convenient because it is a regular cube and therefore easy to map onto the Hilbert curve, but
