{"version":"1.0","type":"rich","title":"Temperature in San Francisco Area chart","description":"An area chart displays temperature in San Francisco over time, with a filled maroon region under a smooth curve. The visualization loads CSV data asynchronously via `d3.csv()`, parsing timestamps and numeric temperatures. It uses `d3.scaleTime()` and `d3.scaleLinear()` for axes, `d3.area()` with `curveBasis` for the smoothed shape, and `d3.axisBottom()` and `d3.axisLeft()` for labeled ticks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/13426698788546d0af5ab136c6832777?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
