{"version":"1.0","type":"rich","title":"First Area Chart","description":"This area chart shows hourly temperature readings in San Francisco over time, with a smooth curved line and a filled region beneath it. The visualization loads data from a remote CSV file using `d3.csv`, parses timestamps with `Date`, and renders the chart as SVG. It employs `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` for axes, and generates the filled area using the `d3.area` generator with `curveBasis`. Axis grid lines, title, and rotated y-axis label are included.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7fb2d9b302d94a4daa520287b40e2529?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
