This example visualizes video game sales data in a 3D scatter plot, comparing North American and Japanese sales across different years and game titles. The code uses Plotly.js to render the scatter3d traces, with two marker series distinguished by color: one for North America and one for Japan. Data is loaded from a CSV file using D3.js’s `d3.csv` function, and the `unpack` helper maps specific columns to the x, y, and z axes. The chart is embedded in an HTML div and styled with a brief CSS file.
