{"version":"1.0","type":"rich","title":"D3 Selection Exploration (1st Stage)","description":"A row of circles oscillates vertically in a sine-wave pattern, with the number of circles shifting over time. The animation uses D3’s selection and data-join methods, calling `svg.selectAll('circle')` with `.data()` and `.join('circle')` to update, enter, and exit elements smoothly. Each frame, `setInterval` generates new data points from `range(n)` and calculates y-coordinates using trigonometric functions, while the SVG canvas fills the browser window.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7928af29669c44ecbb8c9cde0c82c9cf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
