{"version":"1.0","type":"rich","title":"Line chart with multiple dropdowns","description":"This example displays two line charts comparing Olympic medal counts over time for two countries selected from dropdown menus. The visualization uses D3’s `scalePoint` and `scaleLinear` for axes, `flatGroup` to organize data by country, and an ordinal color scale from `schemeSet2` to distinguish the lines. Dropdown menus are populated from the `yearlyData` dataset, and changes trigger redraws via the `viz` function. The chart includes a gray inner rectangle and axes rendered using the `@curran/responsive-axes` library.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fec41273effa468aa22361b0108880f8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
