I made this yesterday. It draws a Hilbert curve in jq. I like jq. gist.github.com/weeble/265cb...

A rainbow Hilbert curve, a squiggly line that visits every cell in a square grid, starting red in the top left, working down then right to becine yellow in the centre, upward and then right to become green at the top right, down and left to be cyan in the centre, and continuing roughly clockwise through blue and the bottom right, magenta off the centre and red again in the bottom left. It's in a terminal and is the result of the command:
jq -rnf curve.jq | rsvg-convert | wezterm imgcat

Source code for the jq script. It's about a page long and uses some pretty opaque variable names like s, sl, t0, dt and dtt. But it does have some text explaining the parameters to its main, recursive "hilbert" function, and we can see that it generates fragments of XML, specifically SVG. The full text is in the linked gist.
