{"version":"1.0","type":"rich","title":"World population area chart","description":"This area chart traces world population over time, showing a smooth upward curve with a subtle leveling in recent years. The visualization pairs an orange filled area with a darker line, and includes circular markers on each data point. Built with D3.js, it uses `d3.area()` and `d3.line()` with `curveBasis` to generate the paths, along with `d3.scaleTime` and `d3.scaleLinear` for the axes. The chart reads population data from a CSV file and renders as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0bbaa317d856418c88afc9c8a4c00203?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
