The example in JSBin does not work

[niko5]

The google-chart example does not word in JS Bin

However if you set it to use version 5.0.0 - 5.0.3 it does.

ie <script type=module src="https://unpkg.com/@google-web-components/google-chart@5.0.0?module"></script>

So there is something not quite right for version 5.1.0 as chart does not render.

There are some issues with unpkg, try esm.run instead:

<script type=module src="https://esm.run/@google-web-components/google-chart"></script>
