{"version":"1.0","type":"rich","title":"Temperature in San Francisco Line Chart","description":"This line chart visualizes the unemployment rates of multiple U.S. metropolitan areas over time, with each area represented by a colored line. The chart uses D3.js APIs such as `scaleTime`, `scaleLinear`, `line` with `curveBasis`, and `axisBottom`/`axisLeft`, and it renders SVG elements. The data is sourced from a static `data.js` file, and the axis labels are localized in Chinese using `timeFormatLocale`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7d3dafcd499b4a17a76208fe0758debd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
