Unicode-based scientific plotting for working in the terminal

Every time I see these things, I wish Sixel graphics[0] were better supported, or else some more modern alternative.

Being able to use GNUPlot with Sixel output or tools like lsix[1] is really cool! I think if support / libraries / knowledge about Sixels was more widespread, we would see some really nifty terminal applications cropping up.

I wrote a generic terminal graphics library that uses Unicode Braille with the option of ASCII fallback: https://github.com/dheera/python-termgraphics

I was thinking about adding sixel support to this to have a universal graphics library that intelligently uses the best method available., but never got around to it yet.

This looks pretty cool. Why isn't this more popular?

Most of the "default" terminal apps (e.g. gnome-terminal) don't support sixel.

What terminal do I need to see these images. I am confused.

The libsixel website lists several that support it. Xterm can support this in VT430 emulation mode, but support needs to be enabled at compile time.
