{"version":"1.0","type":"rich","title":"Heatmap","description":"A heatmap displays average life expectancy for selected countries across seven decades, from 1960 to 2020. Each row represents a country, with colored cells encoding age values using a blue-green gradient where higher life expectancies appear brighter. The visualization uses p5.js, loading CSV data via `loadTable` and mapping numeric values to fill colors through the `color()` function. Country labels and a legend with age ranges are rendered alongside the grid, with axis annotations for years and life expectancy values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bf415a1f5f13495aaf9f79c7c315233f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
