This 3D scatter plot visualizes Walmart sales data by plotting weekly sales, year, and temperature as x, y, and z coordinates. It uses Plotly’s `scatter3d` trace with semi-transparent markers to show relationships between the variables. The data is loaded via `d3.csv` from a GitHub raw URL, and the layout removes all chart margins. The example demonstrates combining D3’s CSV parsing with Plotly’s 3D rendering capabilities in a React-compatible setting, displaying the plot in a dedicated div element.
