{"version":"1.0","type":"rich","title":"7q4","description":"This area chart visualizes life expectancy across countries using the Iris Dataset. The chart employs d3.area() to create a filled region, with a band scale for categorical x-axis positioning and a linear scale for the y-axis. Data is loaded from a CSV file via fetch() and parsed with d3.csvParse(). The SVG rendering uses axis generators d3.axisBottom and d3.axisLeft, with rotated tick labels for readability. The green-filled area emphasizes trends while the fixed y-domain [60, 90] highlights variation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/22346ebc13f44509959d2861e575262b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
