This visualization shows global video game sales by year, using a line chart to plot sales over time. A scatter or line series is configured to map year values on the x-axis and global sales on the y-axis, with axes generated via D3’s `d3.svg.axis`. The code loads CSV data from a GitHub gist, converts the year column into date objects, and groups entries by year using D3’s `nest()` API. The HTML page uses D3 v6 and static SVG rendering, though the drawing is not yet displayed.
