{"version":"1.0","type":"rich","title":"area chart","description":"This area chart displays temperature variations in San Francisco over a two-day period, with time on the x-axis and temperature in Celsius on the y-axis. The filled area beneath the line highlights the daily temperature cycle, rising during the afternoon and falling at night. Built with D3.js v5, it uses `d3.area()` with a `curveBasis` option, `d3.scaleTime()`, and `d3.scaleLinear()` for axes. Data comes from a CSV file loaded via `d3.csv()`, and the visualization is rendered as an SVG with styled grid lines and axis labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dafed5852d734405b7494a8618fd75d7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
