{"version":"1.0","type":"rich","title":"Practice","description":"This example displays a set of animated circles moving vertically and changing size in a sine-wave pattern. The visualization is built with D3.js and rendered as an SVG. The code dynamically generates new data points using a custom `makeData` function, and updates the circle positions and radii via the `vizData` function, which uses D3's `selectAll`, `data`, and `join` methods to efficiently update the scene. The animation is driven by a timer that increments a time variable, causing the circular nodes to oscillate smoothly.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9a09f869c4bc43ca8292937588bebf4b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
