{"version":"1.0","type":"rich","title":"D3 Selection Exploration","description":"Fifteen circles oscillate vertically along a sine wave, their radii pulsing in a related rhythm as time advances. The animation runs continuously, with the wave’s speed steadily increasing. This example demonstrates D3’s selection and join API, using `select('body').append('svg')` to build the scene, `svg.selectAll('circle').data(data).join('circle')` to update circles, and a similar path join to draw connecting lines between adjacent points. The data is generated procedurally with `makeData`, computing x positions from a fixed spacing and y positions from `Math.sin`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7c81ca70a47d455ea5b068f0339d8e44?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
