Show Entity Relationship diagrams of tables in Datasette

## Installation

Install this plugin in the same environment as Datasette.
```bash
datasette install datasette-table-diagram
```
## Usage

Databases gain a new database action menu item called "Table diagram", which links to a page that displays Mermaid Entity Relationship diagrams of the tables in that database.

These diagrams can be panned and zoomed, or users can click a table name to zoom to that table and its relationships.

Users will only see tables that they have permission to view.
