This interactive scatter plot shows the number of countries participating in the Winter Olympics each year from 1924 to 2018. Each circle represents a medal-winning country at a specific Games, with its vertical position reflecting the total participant count for that year. The visualization uses D3.js scale functions and axis components to render the chart, while the data aggregation logic, which counts unique countries per year via JavaScript Set objects, is embedded in the main module. The dataset originates from Kaggle, and the code relies on the `@curran/axis-labels` library for axis annotation.
