{"version":"1.0","type":"rich","title":"Multiple Menus with D3","description":"Three dropdown menus labeled X, Y, and Color let a user select values from a fixed set of car brands, with a message below updating to reflect the current selections. The example uses D3’s `select`, `selectAll`, and `join` to bind the menus and options to data, and a state management pattern with `setState` to track changes across menu interactions. Bootstrap classes provide the layout and styling for the form controls and container.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d608a993c1164745bae3d791b7b9b3ee?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
