{"version":"1.0","type":"rich","title":"World Population Area Chart","description":"This visualization displays global population growth over time using a filled area chart, with the x-axis representing years and the y-axis showing population in billions. The chart uses D3 v5's `scaleTime`, `scaleLinear`, and `area` generator with a basis curve to create a smooth, maroon-filled region beneath the trend line. Axes are rendered via `axisBottom` and `axisLeft`, with grid lines and custom tick formatting converting gigayears to billions. Data comes from a CSV file loaded via `d3.csv`, containing world population figures by year through 2015.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/422b429539674cb384c53f42c65b73ba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
