Javascript (Browser) I recommend opening a blank page (about:blank), then pasting this into the console. It clears the page and creates its own canvas to draw on. You can watch it drawing live, which takes around 30 seconds on my chromebook. (async function() { var canvas = document.createElement("canvas"); canvas.width = 256; canvas....

R, 40 bytes image(matrix(1:0,9,9)[-1,-1],c=1:0,ax=F) This nicely exploits R's argument-recycling to fill a matrix() with dimensions of 9,9 with values of 1:0 recycled to fill it. We then use negative indexing [-1,-1] to chop-off the first row & column. The image() function converts a matrix directly into a coloured image. Here we specify the color as ...

There are some 'wasted' pixels at the top & on the left (so the curve is in the top left corner but not touching the edge). This seems to be within the spec, but could be removed for +13 bytes. ...
