This chart demonstrates a staged approach to data visualization, showing how different visual encodings can convey information. The first stage uses only x and y positions to map game attributes, while the second adds color to distinguish between genres. The third stage incorporates circle size to represent sales figures, creating a multi-dimensional scatter plot. The visualization is built with D3.js version 7.8.5 and renders as SVG, with interactive controls allowing users to toggle between the three stages.
