{"version":"1.0","type":"rich","title":"Interazione con flusso di dati unidirezionale - Original","description":"Five circles render as apples and animate with transitions as data changes. When clicked, the selected fruit gets a black stroke. The dataset shrinks, one apple mutates to a lemon, and another element is removed across timed updates. Using D3 v5, the code applies a data join with `selection.data`, `enter`, `merge`, `exit`, and `transition.attr` to update SVG circle positions, radii, and colors based on ordinal scales.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c7d8ce90a4234bbaa55500b538130e37?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
