This bubble chart displays the correlation between average potassium, sodium, and carbohydrate levels across different breakfast cereals. Each circle represents a cereal brand, with its position determined by potassium and sodium values, while its radius encodes carbohydrate content and color maps to the cereal name. The visualization includes interactive tooltips that appear on hover, as well as legends for both circle size and color. Implemented with D3 v7, the chart loads data from a CSV file, uses SVG for rendering, and employs d3.scaleLinear, d3.scaleOrdinal, and d3.interpolateTurbo for visual encoding.
