{"version":"1.0","type":"rich","title":"Area Chart","description":"This area chart visualizes temperature in San Francisco over time, with a gradient-filled path showing the trend and labeled axes for date and temperature. The visualization is built with D3 v6, using `scaleTime` and `scaleLinear` for the scales, `area()` with `curveBasis` to generate the smooth area path, and `axisBottom` and `axisLeft` for the gridlines. Data is loaded from a CSV file via `csv()`, and the SVG rendering includes custom gradients defined in the markup.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5a546f3e7b1d44bdb4a163d6f78e8e7c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
