{"version":"1.0","type":"rich","title":"Total Number of Rockets Throughout The Years","description":"This bar chart shows the total number of rockets launched each year, using bar height to represent the absolute count of launches over time. The visualization aggregates the dataset from Kaggle's global space launches by grouping records by year and counting occurrences with `vl.groupby` and `vl.count` in vega-lite-api. The chart uses D3 v5 via `d3.csv` for data loading, while rendering is handled through vega-lite and vega with SVG output. Bars encode the count as quantitative values on the y-axis, with years on the x-axis, and tooltips provide exact counts for each year.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c73788d9f4a04f068e65f7ac536a7b89?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
