{"version":"1.0","type":"rich","title":"Fork of Multiple Menus with D3","description":"Three dropdown menus let a user independently select values for X, Y, and Color from a fixed set of car brands. The example shows how to generate multiple synchronized `<select>` elements with D3’s selection and join operations, using `d3.select` and `.join` to manage the menu lifecycle. As the user changes an option, a text message updates to reflect the current combination of chosen attributes, demonstrating a reusable `menu` function that binds each dropdown to a separate field in the shared state object.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3b4da898cb434a31af27b4924cac456a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
