{"version":"1.0","type":"rich","title":"Stacked barchart","description":"This stacked bar chart shows the total number of rockets launched per year, with each bar segment colored by company name to reveal mission success or failure. It uses Vega-Lite’s API via `vl.markBar()` and `vl.transform.groupby` to aggregate counts, while encoding year on the x-axis and rocket count on the y-axis. The data comes from a CSV of global space launches, and the visualization integrates multiple tooltip fields for Count and Company Name. Styling is customized through a config file that adjusts axis ticks, label sizes, and dark text colors for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d6fc79b3f82940ac9163aa30562f6576?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
