This scatter plot shows the relationship between alcohol content and quality scores for white wine samples, with each circle representing an individual wine. A reusable `scatterPlot()` function in D3 v7 builds the SVG chart, using `d3.scaleLinear` for both axes and `d3.axisBottom`/`d3.axisLeft` for tick marks. The chart loads CSV data from a GitHub gist, parses the numeric columns, and renders semi-transparent steelblue points. The function exposes getter/setter methods for width, height, value accessors, and color, demonstrating a configurable chart pattern.
