This visualization shows global video game sales by year, with bars colored by genre to reveal sales trends across categories over time. It uses the Vega-Lite API with D3’s CSV loader to fetch data from a GitHub-hosted dataset originally sourced from Kaggle. The chart encodes years on the x-axis, global sales on the y-axis, and genre as color, with tooltips displaying genre names. Custom styling via a config object improves label and title readability, while Vega-Lite’s automatic rendering handles the bar marks and scales.
