{"version":"1.0","type":"rich","title":"LineChart with Multiple Lines","description":"A multi-line chart displays a week of temperature readings across multiple cities, with each city represented by a distinct colored line and a color legend. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, `line` generator with `curveBasis`, and `nest` to group data by city, while `axisBottom` and `axisLeft` render labeled axes. Data is loaded from a CSV file, and the chart is drawn as SVG with a title and a custom color legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/80a9dc2c4ca9496aa661d3502691a9c1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
