{"version":"1.0","type":"rich","title":"Word Cloud Example","description":"This example visualizes the frequency of family and first names from genealogical data using D3.js word clouds. The visualization displays the most common names as text, with font size scaled proportionally to their occurrence count, rendered in an animated layout using SVG. The implementation leverages the `d3.layout.cloud` module, which uses a canvas's `getImageData` method for text bounding measurements, along with the `d3.scale.linear` for size mapping and `d3.scale.category20` for coloring. Users can switch between datasets via toolbar buttons that load different JSON files.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/742129b292c34dd59afaaeef5ee2ce87?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
