An idea: A Pulumi sandbox for testing resource declarations, akin to codepen, but only running pulumi preivew / generating a dependency graph diagram as the output from interpreted declarations, https://codepen.io/ or https://www.online-ide.com/ Or a fully preconfigured environment, such as this CodeSandbox would be super cool https://codesandbox.io/s/github/quasarframework/quasar-codesandbox/tree/master
