{"version":"1.0","type":"rich","title":"Line chart with multiple lines","description":"This line chart displays the number of reviews per state across the days of a year, with multiple colored lines representing individual states. The visualization includes an interactive color legend that highlights a selected state while dimming others. Built with D3 v5 and rendered as SVG, the code uses `d3.csv` for data loading, `d3.nest` for grouping by state, and `d3.line` with `curveBasis` for smooth lines. Axis labels and a title are added, while the legend is implemented through a custom `colorLegend` function. The underlying data comes from the provided external CSV dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2d0b31cd4f254c7c93db3324c12872e1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
