{"version":"1.0","type":"rich","title":"D3 Starter - d3.nest()","description":"This example demonstrates how to group and structure an array of car objects using the `d3.nest()` function. It defines four car records with name, manufacturing year, and model, then applies a key function on the `manufactured` property to create hierarchical groups. The resulting nested data structure is logged to the browser console, showing how entries are organized by year. The code uses D3 version 4 and executes entirely in the console without any visual rendering on the page.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
