{"version":"1.0","type":"rich","title":"Menu with D3","description":"This example demonstrates how to add an interactive dropdown menu to a D3 visualization, showing the selected car brand as a text message. It uses D3’s data-join pattern to bind menu options to a `select` element, updating the displayed text when the selection changes. Bootstrap’s `form-select` class styles the dropdown, while D3’s `on('change')` listener updates the application state via the `setState` function. The code highlights a clean separation between UI rendering and state management, making it a practical template for incorporating menus into larger D3 projects.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/52f5d7aee9d24206a7429f00725c3806?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
