I love this kind of thing. This is a representation of a knitting stitch pattern that is close in appearance to the actual knitting... if knitting existed in Flatland. I could knit from this diagram... but I'm not sure if anyone else could.
I create this diagram from a graph of the knitting pattern, so this is an intermediate representation of sorts.
To convert this diagram to a 3-d representation of knitting (or the knitted piece itself) would require more information. This diagram doesn't keep track of which are knit stitches and which are purl stitches.
Also, in the diagram the knitted decreases are ambiguous. When you knit a decrease you're pulling a loop through two or more loops from the previous row. One of the loops from the previous row ends up on top of the fabric, partially covering the other loop or loops. It's not shown which loop of the previous knitted row ends up on the top of the fabric.
On the other hand, Shetland lace knitters' directions were at about this level of information... you got a list of Knit stitches, Make 1's and Narrows, and the fabric was implied garter stitch. If you're knitting something with the extremely fine yarn and small needles that the Shetland lace knitters used, it doesn't much matter which knitted decrease you use, the decreases are so tiny.
