{"version":"1.0","type":"rich","title":"Let'Test selection D3 !","description":"This example demonstrates how D3 selections manage the lifecycle of SVG circles through enter, update, and exit phases. Randomly generated data from a custom `data` function initially renders five blue circles, which are then updated to grey with a fixed radius of 11. The code explicitly uses `d3.select('svg')`, `.selectAll('circle')`, `.data()`, `.enter()`, `.exit()`, and `.remove()` while applying chained attribute and style modifications. Although an update with ten circles exists, it remains commented out, so only the initial static rendering is visible.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/102b995e3b614e4aaf9a828c071d7cbd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
