anyway i'm making a sankey diagram from scratch because: • i wanna have overlapping flows to multiple sinks • i wanna animate it

so fun fact about sankey diagrams: one way you used to make them was by cutting ribbons of paper and then bundling those on edge and placing it on photographic paper and exposing it: since the thickness of the (edge) paper was known you could represent accurate ratios

still very much in the "how do i want the underlying data structure to be" stage of things so i'm just drawing straight lines at the y-values of the (one-dimensional i guess) centroids of the nodes

what i'm doing here is just plunking down straight lines where i want the series of sankey tubes to go, this time i just made the stroke width proportional to the flow (the heights are still not quite right so i'mma fix those then replace the lines with béziers)
