{"version":"1.0","type":"rich","title":"072119-9:03 World Population Area Chart - Sunday 072119","description":"This area chart displays world population growth from 1960 to 2015, using a maroon filled curve above a time-based x-axis and a population y-axis labeled in billions. The code loads CSV data via `d3.csv`, parses years as `Date` objects, and renders the SVG through D3 v5’s `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `area` generator with a `curveBasis` smoothing. Grid lines and rotated axis labels are added, with tick formatting converting values from billions to shorthand. The visualization is built entirely with SVG and D3 selections.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/41b7350079db4c08b1c2f7d239238b67?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
