An interactive bar chart displays sales percentages for ten video game genres, from Racing at 78.9% to Misc at 59.6%. Built with D3.js v5, the SVG chart uses a custom `d3.scaleBand` and `d3.scaleLinear` for axes. Hovering a bar triggers a transition that dims and expands the bar, adds a dashed limit line at the hovered value, and annotates each bar with its percentage difference from the selected genre, using `d3.select` and `.attr('opacity')`. The data is a sample of the Video Game Sales Dataset.
