james-revisionai captured most of the main ideas.

One thing not emphasized well:

1. Make it accessible. At some point, virtually all of us will have some form of accessibility issues. 508 compliance is a solid standard for this, though can be a pain to manage without starting with it from the get-go.

2. Make it tabbable (similar to accessible).

3. For development side, make it able to client-side OR server-side render -- not every dashboard will have or need a rendering server. In python, Altair is the only client-side rendering that is also interactive that I'm aware of. It's important for payload considerations

4. Related to 3 - consider payload considerations. Make it transparent, either in debug logs or similar, how large the elements passing across the wire are.
