{"version":"1.0","type":"rich","title":"SVG Fundamentals","description":"Four overlaid rounded rectangles demonstrate core SVG fundamentals within a D3.js v5 environment. The visualization shows two overlapping shapes with varying corner radii, positioned using both pixel and viewport-height units. One red and one green rectangle dominate the center, while a pair of small vertical bars in red and green sit offset to the right, each with distinct dimensions. The code explicitly defines the SVG canvas, `rect` elements, and fill attributes, while a separate script imports D3’s `select` function and a local module to display a text message.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3204b7c0d6ab469b9bd1a5ade34cdee1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
