Examples: on CodeSandbox.io

[fahad19]

Create some examples on https://codesandbox.io/, and see if we can even embed them in our docs.

Making it easier for others to try things out.

@fahad19 I see you made some examples on codesandbox, maybe we should create an examples page and display them there via codesandbox?

Good idea. The examples page can mention the ones that exist in the monorepo, as well as the ones we host on codesandbox too.
