{"version":"1.0","type":"rich","title":"InfoVis proj","description":"This bar chart shows the total number of rocket launches per year, broken down by company, using a global space launches dataset loaded from a CSV via `d3.csv`. The visualization uses a stacked bar mark with Vega-Lite, encoding the year on the x-axis, the count of launches on the y-axis, and company name for color. Data is aggregated with `groupby` and a count operation, and the chart is rendered with SVG, using vega-tooltip for interactive hover details.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6853c4640b944ce2a636dd3a089c5460?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
