In my quest to make VizHub awesome, one of the forefront features is JSX support. Initially, Bublé was added, as this seemed the path of least resistance. Unfortunately, this adds quite a bit of heft to the overall VizHub app bundle. This chart is an exploration of comparative bundle sizes for various means of transpiling JSX into JS, for potential use within VizHub as its "JSX Engine". Bundlephobia.com was used to get bundle size (minified, not GZipped) for each package.
