{"version":"1.0","type":"rich","title":"Area chart","description":"This area chart visualizes world population trends from 1950 to 2015, with the x-axis mapping years and the y-axis representing population counts (in billions). The chart uses a smooth curve to fill the area beneath the population line. Built with D3 v5, it employs `scaleTime`, `scaleLinear`, `area`, and `axisBottom`/`axisLeft` to render the SVG. Data is loaded asynchronously from a CSV file via `d3.csv`, with population values parsed as numbers and years as dates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/11b6a5c2026f4c8ba6bbe01b613c671f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
