This bubble chart visualizes sales records by country, with circle size encoding total profit and color mapping regions. The tidy, evenly spaced layout derives from a D3 hierarchy and pack layout (d3.pack), which positions the data points without overlap. Each circle displays its country name as a label. The visualization loads its data from a CSV file using d3.csv and renders as SVG. Interactive tooltips appear on hover, displaying the country and profit values via D3 event handlers and HTML tooltip elements.
