                The `description` argument allows you to add helpful context to your components by displaying a small
                info icon next to the component's title.
                When users hover over the icon, a tooltip appears showing the text you provide.

                You can add tooltips to any Vizro component that supports the title argument. The description accepts:
                * A `string`, which uses the default info icon.
                * A `Tooltip` model, which lets you customize the icon using any symbol from the
                [Google Material Icons library](https://fonts.google.com/icons)

                Tooltips are a clean, lightweight way to offer additional details without cluttering your dashboard.
