{"version":"1.0","type":"rich","title":"Number of Missions by Year and Country with an Interactive Color Legend","description":"This scatter plot displays the number of space missions per year, with each country (USA, Russia, China, Kazakhstan) represented by a distinct color. An interactive color legend allows hovering over a country name to highlight its corresponding circles while fading others. The visualization uses D3 scales (`scaleTime`, `scaleLinear`, `scaleOrdinal`) and React components for rendering SVG circles grouped by year. Data comes from a Kaggle CSV file processed with D3’s `csv` and `nest` functions, with axes and legend developed as custom React components.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/af177a5813b14088baaf2a987141bee0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
