This chart displays the number of game-platform release records per year between 1980 and 2015, as compiled from a CSV dataset. The line graph rises and falls across the timeline, revealing peaks and troughs in game releases. The visualization is built with D3 v7, using `d3.csv` to load the data, `d3.group` to count records by year, and D3’s time scale and axis functions to render the SVG line plot. Animated transitions and interactive tooltips highlight each year’s count on hover.
