Total Number of Rockets Throughout The Years
This visualization shows the total number of rockets launched each year, with bars colored by the company’s country of origin. It uses a bar chart with a count aggregation grouped by year and country, displaying tooltips for the count and country on hover. The code relies on Vega-Lite API, Vega, and d3.csv to load and process data from a GitHub-hosted CSV file, with a custom config adjusting axis styles and font sizes for readability. The visualization renders in an SVG view fitted to the browser window.
