{"version":"1.0","type":"rich","title":"10_Temp in San Fran Area chart","description":"This area chart shows a week of temperature readings in San Francisco, with the maroon-filled area under a basis spline curve revealing the overall trend over time. The chart uses `d3.scaleTime` and `d3.scaleLinear` for the axes, `d3.area` with `d3.curveBasis` to generate the smooth filled path, and `d3.scalePoint` for the overlaid semi-transparent blue circles marking each data point. The data is loaded from a CSV file, with timestamps parsed as dates and temperatures as numbers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/326a09d9833841aea7b326b051670814?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
