The visualization is built with the Vega-Lite API (vl) on top of Vega and Vega-Lite, rendering to SVG. Data is fetched as CSV via d3.csv from a remote gist, then unfolded into long format with Year and Population fields. Tooltips, provided by Vega-Tooltip, show the country name on hover, while a custom config adjusts axis and label styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f1e010ab689f4e3cb20ec1aacd584594?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
