{"version":"1.0","type":"rich","title":"World Population Area Chart (d3)","description":"This area chart visualizes global population growth over time, with years on the x-axis and population on the y-axis, using a smooth filled curve to show trends. The code employs d3’s `area`, `scaleTime`, `scaleLinear`, and `axisLeft`/`axisBottom` APIs to render the SVG, while formatting y-axis labels in billions. Data is loaded from a CSV file and parsed into date and numeric values. The chart includes custom axis styling, grid lines, and a centered title.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c0d17c29c9554e16b6e433ecb335e702?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
