{"version":"1.0","type":"rich","title":"Fork of A week in San Francisco - Line chart","description":"This visualization displays course demand statistics as multi-line time series, with each line representing a different course ID and tracking count values over dates. The chart uses D3 v5 with SVG rendering, employing `d3.nest()` to group data by course ID, `d3.line()` with `curveBasis` for smooth paths, and `scaleTime`/`scaleLinear` axes. A color legend appears on the right, generated by a custom `colorLegend` module, while the data is filtered to show only the first three courses from a CSV source.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/df950398eb78406b8a864dc3f6133f1e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
