{"version":"1.0","type":"rich","title":"Wind chart","description":"A circular wind rose chart visualizes directional wind speed data as stacked radial bars around a central point, with each bar segment colored by speed category and labeled around the perimeter. Built with D3 v5, the visualization uses `d3.arc()` for the radial segments, `d3.scaleBand()` for angular positioning, and `d3.stack()` to layer the speed components. The data originates from the Data Canvas - Sense Your City project. A legend and circular grid lines with radial axis ticks support interpretation of the magnitude and direction of the wind measurements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5d113c934de34980af27214f95b23e5a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
