The visualization uses D3 v6 to render an SVG, employing `scaleTime` and `scaleLinear` for the axes, an `area` generator to create the filled region, and `axisLeft`/`axisBottom` with gridlines. The chart features a clear title, labeled axes with formatted tick values, and an orange semi-transparent fill to highlight the population trend over time.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/99c88fe59ea145acad04f36f8d4bf1fa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
