{"version":"1.0","type":"rich","title":"World population","description":"This area chart shows world population over time, with the x-axis mapping years and the y-axis displaying population in billions, using a filled path with a smooth curve. The data comes from a CSV file loaded via `d3.csv`, and the visualization leverages `d3.scaleTime`, `d3.scaleLinear`, `d3.area`, and `d3.axisBottom`/`d3.axisLeft` to render an SVG. A custom tick formatter converts values from billions to a shorter notation, while grid lines and axis labels are styled through CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1e22095ac9b64dcb84a4bbdea766df61?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
