This bubble chart visualizes sales records by country, with circle size representing total profit and color encoding country. Each bubble displays its country name as a label. The visualization uses D3 v7's `d3.pack` layout and `d3.hierarchy` to calculate circle positions and sizes from the CSV data. Interactive tooltips appear on mouseover using HTML and D3 event handlers. A save button clones the SVG and downloads it as a file, preserving computed styles. Data is loaded via `d3.csv` from a gist URL, and the chart is rendered as an SVG in a React-based HTML page.
