Add descriptions to visualizations #20936
Description
To better improve the experience of larger organizations with 1,000's of visualizations as well as the default module experience, I'd like to allow the visualization creators to add some additional meta data that helps explain the visualization. We can do this with dashboards today, but it would be great if we could enable the same feature for visualizations.
Luckily, the description field actually already exists as part of the JSON object.
In order to support this feature we'd need to provide a similar UI experience that dashboards do today.
Entering a description in the description field would simply update the JSON field and then visualize in the list page.
Given that the visualization list has an extra column, we may have to explore ways of truncating the description and providing a tooltip for the full description.
As a nice to have (and previously requested feature) it would also be great to utilize this description from the dashboard view mode through a tool tip. This would significantly help the experience of a new user jumping into a dashboard for the first time.
