{"version":"1.0","type":"rich","title":"Several City Chart","description":"This chart displays a week of temperature readings from multiple cities, with each city drawn as a colored line over time. The data is loaded from a CSV, parsed, and rendered as smoothed SVG paths using d3.line with curveBasis. Axes are generated with d3.axisBottom and d3.axisLeft, and a color legend is built using d3.scaleOrdinal with schemeCategory10. React manages the app shell, while d3.nest groups records by city for sorting.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c381372ed02f4805bf4d3a52eaf1e5e3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
