Spells which are danced are not uncommon, and that drawing is lovely.
There were some Sufi sects that used this method (and of course the 'whirling Dervishes' were a thing, using their magico-religious dance to induce an ecstatic state in which magic could be more easily accessed, and to raise power). Some styles of magic in India, Nepal and Polynesia use dance both to raise power and to shape the pattern of the spell, because most styles of magic depend on shaping power within some kind of pattern, whether that pattern be shaped from words, music, dance, runes or knots. Sort of like building a circuit board.
There are Native American styles of magic that use dance, and out here we have peoples such as the Myrning of the Nullarbor, who have the interesting usage of first laying out a pattern on the ground, usually by sprinkling sand, dancing the pattern over the course of a night, then using that shaped energy to power traditional practices. Early European anthropologists believed that the Myrning 'had no culture' because their practices left no physical artifacts, nothing like inscribed runes or carved charms, but they have culture well enough.
