{"version":"1.0","type":"rich","title":"Untitled","description":"This interactive line chart displays temperature data through time, with a dropdown to switch between Fahrenheit and Celsius scales. The visualization renders multiple city temperature series as smooth cardinal curves, using D3 v5 with SVG and animated transitions. A mouse-over interaction uses a bisector to find the nearest date, displaying a vertical guide line, value labels, and colored circles for each city at the hovered position. The y-axis updates dynamically with the selected metric via a smooth transition.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6f2977f64f964b3b9e1dcc5143b0152f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
