{"version":"1.0","type":"rich","title":"Temperature in San Francisco Areachart","description":"This area chart shows daily temperature fluctuations in San Francisco over a month, with a smooth curve tracing values from 31 to 87 degrees. The visualization uses D3.js v7 APIs including `scaleTime`, `scaleLinear`, `area`, and `curveBasis` to generate the filled path, while `axisBottom` and `axisLeft` add labeled axes with gridlines. Data comes from a local CSV file parsed via `csv()`, and the chart is rendered as SVG within a fixed 960×500 viewport. The maroon area fill emphasizes the temperature range beneath the curve.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b405cb7dd28b420c938efd97ba7231fb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
