{"version":"1.0","type":"rich","title":"Wind Rose Starter","description":"This wind rose visualization displays the frequency and direction of wind speeds, with eight speed categories (from 0-1 to 6+ units) arranged as concentric rings around a central point. Each of the 16 compass directions (N, NNE, NE, etc.) is represented as a wedge, colored by speed category using `d3.scaleOrdinal()`. The chart uses `d3.arc()` with `innerRadius` and `outerRadius` from a `d3.scaleLinear()` to draw stacked radial bars, and includes circular gridlines and angle labels. Data is loaded from a CSV file with `d3.csv()`, and the visualization is rendered as SVG, with an optional `scaleRadial` function from the included `d3-scale-radial.js` file available for alternative radial scaling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/43f9e33a5fe74692a09b6a6f3862b805?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
