{"version":"1.0","type":"rich","title":"Fork of Selecting a Year on a Line Chart","description":"This interactive line chart displays population trends over time for various world regions, with a vertical line marking a selected year, which users can adjust by moving the mouse across the chart. Using D3 v5, the visualization employs `scaleTime`, `scaleLinear`, and `scaleOrdinal` for scales, `axisBottom` and `axisLeft` for axes, and `line` with `curveBasis` for smooth paths. Data is loaded from UN population estimate CSV files. The SVG rendering updates dynamically through a selection state, and a separate color legend uses `scaleOrdinal` with a category 10 scheme to identify regions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/598a71d43973476ba0318194752fc1dd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
