This visualization plots global sales of video games against gaming platforms using a circular scatterplot. Each circle’s position encodes the platform on the y-axis and the game’s global sales on the x-axis, with opacity used to show overlapping points. The chart uses Vega-Lite and the vega-lite-api to construct the markCircle encoding, while d3.csv loads the Videogame Sales dataset from a GitHub gist. Tooltips display game names on hover. The visualization is rendered as an SVG, with config.js customizing axes and text styling.
