{"version":"1.0","type":"rich","title":"D3 Tutotial Video 5 Viz","description":"A pulsing ring of fifteen translucent circles animates in a looping orbit around a central point. The visualization demonstrates D3.js’s declarative join operation, where each frame’s data array maps to circle positions and opacity values derived from trigonometric functions. Using `selectAll('circle').data(data).join('circle')`, the code updates circle attributes at 60 frames per second through `setInterval`, with a time variable `t` incrementing to drive continuous motion. The SVG rendering fills the browser window, showcasing dynamic, data-driven animation without user interaction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f1f6eba949544e21b86e14bd1eda4dce?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
