{"version":"1.0","type":"rich","title":"Area Chart:World Population","description":"This area chart visualizes world population growth over time, with the area fill representing population counts and a line tracing the trend. The code uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `area` with `curveBasis`, and axes with tick formatting that converts billions to \"B.\" It loads CSV data from a VizHub dataset, parses years as dates and populations as numbers, and renders the SVG chart with custom axis labels, tick lines, and styling for the title and area path.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/94ce9b466131447ea90fb1f30f693a14?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
