{"version":"1.0","type":"rich","title":"Smiley Face Part II","description":"This example shows a red line segment positioned at the center of the viewport, with an additional red line appended to an SVG via D3’s selection and `attr` methods. The React component renders an SVG with a `line` element, while a separate D3 `select` chain creates a second line with fixed coordinates. The code uses React 16.9, D3 v5’s `select`, and inline SVG attributes, with window dimensions determining the centering transform.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5b993d552e5c423ab154ccc5da9f67a8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
