{"version":"1.0","type":"rich","title":"Total Sales of Video Games by Genre","description":"This line graph shows total video game sales by genre over time, with an interactive dropdown to switch between global, North American, European, Japanese, and other regional sales figures. The visualization uses Observable Plot’s `Plot.line` and `Plot.frame` to render the SVG marks, alongside D3’s `rollup` and `sum` for data aggregation. A custom color legend is generated via `Plot.cellX` and appended to the chart. The dataset comes from the Video Game Sales Dataset prepared by Daniel Ribaudo.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f22da35729284005bdeb38b97cfbe3ce?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
