{"version":"1.0","type":"rich","title":"World population by year 2014","description":"An area chart displays world population from 1950 to 2015, using a smooth basis curve to fill the space beneath the line. The visualization loads data from a CSV file and renders it with D3.js v5, using `scaleTime` for the x-axis, `scaleLinear` for the y-axis, and `area` with `curveBasis` for the shaded region. Grid lines and axis labels are drawn via `axisLeft` and `axisBottom`. The title and axis texts are styled using CSS classes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f0d4a1aecbe44aafb4b20617846d9111?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
