{"version":"1.0","type":"rich","title":"Fork of Selecting a Year on a Line Chart","description":"This visualization displays population trends over time for multiple world regions, using a line chart where each colored line represents a different region. Users can hover over the chart to select a specific year, which is marked by a vertical line and updates the visualization accordingly. The implementation uses D3 v5 with SVG rendering, employing scales like `scaleTime` and `scaleLinear`, the `line` generator with `curveBasis`, and a `nest` operation to group data by region. Data comes from UN population estimates and medium variant projections, processed with the `csv` loader.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c65fc3fc06b3469aa59cf81e7dbe817b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
