{"version":"1.0","type":"rich","title":"Letras animadas","description":"This example demonstrates D3’s selection.join pattern with animated transitions for entering, updating, and exiting letters. It generates a shuffled, sorted subset of the alphabet every second, rendering each letter as a text element colored green when entering, black when updating, and brown when exiting. The code uses `d3.select`, `d3.transition`, and `d3.shuffle` to animate vertical and horizontal movement, with a `setInterval` loop and a cleanup function that works with hot reloading.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
