This bubble chart maps 12 best-selling video games by critic score on the x-axis and user score on the y-axis, with bubble area scaled to global sales (in millions) using d3.scaleSqrt. Each point is colored by genre. The chart uses d3.v7’s selection, scale, and append methods to build an SVG, with axis labels, a legend, and a hover tooltip for details. Data is a small custom set of well-known games.
