This visualization aggregates Walmart weekly sales data by temperature bins, smoothing the resulting points into a blue basis-spline line chart. It uses D3 version 7 APIs including `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` to render the SVG. The chart plots temperature in Fahrenheit on the x-axis against total weekly sales on the y-axis, with the data sourced from a CSV hosted on GitHub. Axis labels and a title annotate the plot, which lacks interactive features.
