{"version":"1.0","type":"rich","title":"Fork of Smiley face part 1","description":"This example shows a static green rectangle drawn on a red SVG background, representing the first step toward a smiley face. The visualization uses React with D3 v6, where the `select` API targets the SVG element and `append` adds the rectangle with explicit width, height, fill, and stroke attributes. The code also loads a CSV file containing population data for ten countries using `csv` from D3, converting the population values to numbers. However, the loaded data does not currently influence the rendering, leaving the rectangle as the only visible output.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bdc017b8fef04d4aa7df9221434fcf02?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
