{"version":"1.0","type":"rich","title":"World Population Area Chart","description":"This area chart shows world population growth over time, with the x-axis representing years and the y-axis showing population in billions. The chart uses a smooth curve via d3.area with curveBasis, filling the area beneath the line in maroon. It loads CSV data from a VizHub dataset, parses years as dates and populations as numbers, and renders axes with d3.axisLeft and d3.axisBottom. The SVG output includes gridlines, axis labels, and a title, all styled through external CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7d941927febb4161a4d084bb378e58a0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
