{"version":"1.0","type":"rich","title":"Wind Rose Starter Playtime","description":"This wind rose visualizes wind speed and direction using stacked radial bars. The wind speed bins are shown as colored segments, with direction labels placed around the circular plot. The code uses `d3.arc()` for the bar geometry, `d3.stack()` to layer the speed categories, and `d3.scaleOrdinal` for color mapping. Data comes from a CSV file, with circular grid lines drawn via `d3.axisLeft`. The custom `d3-scale-radial.js` library is included but the main visualization uses standard linear scales for radius.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4e28c7f1812341059a1ff97102edff04?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
