{"version":"1.0","type":"rich","title":"World population","description":"This example displays world population trends over time using an area chart, with the x-axis representing years and the y-axis showing population counts. The visualization renders as an SVG with a maroon, partially transparent filled area and axis labels. The code uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `area`, `axisBottom`, `axisLeft`, and `curveBasis` for smoothing, and loads population data from a CSV file. The dataset spans multiple years, with values formatted using `d3.format`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/06c7b1e4924446c69c583c6b86cb245e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
