Stacked barchart
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.
