{"version":"1.0","type":"rich","title":"A week in San Francisco - Area Charts","description":"This example visualizes a week of temperature data in San Francisco using a filled area chart. A smooth, maroon area curve spans the time axis, with gridlines and labeled axes for time and temperature. The visualization uses D3 v5 APIs including `d3.area`, `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft`, rendering to SVG. Data is loaded asynchronously from a remote CSV file, with timestamps parsed as dates and temperatures converted to numbers. The `curveBasis` interpolation smooths the line.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c31e3892b30546668b295fa834c8d2dd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
