This visualization displays promotional metrics for various locations, using circles positioned diagonally across an SVG canvas. Each circle's size represents the headcount at that location, scaled by dividing the value by 80. The chart is rendered with D3 v6, using selections to append circles to an SVG element and binding data loaded from a CSV file. The code also converts percentage columns by multiplying them by 10, though these transformed values are not used in the final rendering.
