Vals using react-dom/server

@jsxImportSource https://esm.sh/react

Server-Rendered React Sparkline Example Vaguely inspired by Easy SVG sparklines , but totally different because that had zero dependencies and this has all the dependencies: react, htm, react-sparklines. This is the live-generated SVG that this very val generates:  It visualizes the amount of times that it itself has been viewed. The data for this val is kept in @stevekrouse.sparklineExData .
