A scatterplot shows wine quality ratings along the x-axis against alcohol content on the y-axis, with each wine represented as a semi-transparent golden circle. The visualization uses D3 v7’s `scaleLinear`, `axisBottom`, and `axisLeft` to map the data, which is loaded from a semicolon-delimited CSV file. The source data contains wine attributes like fixed acidity, pH, and sulphates, though only quality and alcohol are plotted. The SVG rendering includes gridlines and labeled axes, with circles sized at a fixed radius of 10.
