I've used a similar technique to implement one of the graphs for small "header dashboard" for a trading tool at my previous job. It was replacing an old decrepit tool and I wanted to add some pizzaz to the tool, and had an obsession with SVG and micro interactions at the time, so I've basically implemented most of the little graphics using hand-emitted SVG that was manipulatied through React. The updates happened in one batch too, so the performance was always great
