{"version":"1.0","type":"rich","title":"Line Area Chart","description":"This visualization shows a week of temperature fluctuations in San Francisco using a filled area chart, with time on the x-axis and temperature on the y-axis. The chart displays a smooth, curved area in maroon, with labeled axes and a clear title. Built with D3 v7, the code uses `d3.area`, `d3.curveBasis`, `d3.scaleTime`, `d3.scaleLinear`, and `d3.axisLeft`/`d3.axisBottom` to render the SVG. Data is loaded as CSV from a VizHub dataset, with timestamps parsed as dates and temperatures converted to numbers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bcfe8ec70f9e4bc8b876a85ca0c54677?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
