{"version":"1.0","type":"rich","title":"Selecting a Year on a Line Chart","description":"This line chart displays population over time by world region, with each region represented by a colored path and a color legend. The visualization allows selection of a specific year by clicking on the chart, which updates the display accordingly. Built with D3 v6, the chart uses `scaleTime` and `scaleLinear` for axes, `line` with `curveBasis` for smooth paths, and `scaleOrdinal` with `schemeCategory10` for colors. The data comes from UN population estimates, processed by melting wide-format CSV data into tidy rows.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0c669b3d76534fc5a75d73852862654c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
