{"version":"1.0","type":"rich","title":"D3-Demo","description":"This example demonstrates the fundamental setup of a VizHub version 3 project, featuring a blank SVG canvas with a single white rectangle. The code uses D3.js v7 to select the body, append an SVG element, and draw a rectangle positioned near the top center.
