{"version":"1.0","type":"rich","title":"Count of countries based on each region and year","description":"This visualization shows the count of rocket launches aggregated by country region across years, using a grouped bar chart where each bar’s length represents the total number of rockets and its color distinguishes the region. The chart is built with the Vega-Lite API (`vl.markBar()`, `vl.x()`, `vl.y()`, `vl.color()`), applying a transform that groups data by both year and region before counting occurrences. The data is loaded via `d3.csv()` from a GitHub-hosted CSV file sourced from Kaggle, and the rendering uses Vega’s SVG output with custom tooltips and axis styling from the provided configuration.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b030ffb4360b4570a663a71c21368139?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
