{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart visualizes a week of temperature data in San Francisco, using D3 v5 to render an SVG. The code loads CSV data from a remote URL, parses timestamps and numeric temperatures, and scales the axes with `scaleTime` and `scaleLinear`. It draws a single smoothed line via `d3.line` with the `curveBasis` curve, and includes styled grid lines, axis labels, and a title. The line path uses a thick gray stroke, while the axis tick labels and titles are styled through CSS classes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d2dc56a5d74c46f9b58005bd5c137b7f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
