{"version":"1.0","type":"rich","title":"Menu Example","description":"A dropdown menu offers six color choices, while a scatter-like column of circles encodes two fixed numeric datasets. The circle positions and colors update only when the menu selection changes. Built with D3 v7, the example uses a `select` join to bind options, `interpolateRdYlGn` for the circle fill gradient, and custom `menu` and `treeCoder` modules to render the SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f98e0dae1b544514be3ae00fd5462e9e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
