{"version":"1.0","type":"rich","title":"Line chart","description":"This line chart visualizes temperature changes in San Francisco over time using a smooth curved line, with time on the x-axis and temperature on the y-axis. It loads CSV data from a `vizhub.com` dataset and renders with D3 v5’s `d3.line`, `d3.scaleTime`, and `d3.scaleLinear`. The SVG output includes axis labels, a title, and grid lines, with styling defined in CSS. The data is preprocessed by parsing timestamps and numeric temperature values before rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/762152d3d2a74240b7b0666085de02f2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
