This scatter plot visualizes the relationship between color and intensity attributes of wines from the Wine Recognition dataset. Each point’s position encodes the two quantitative variables, while its fill color and symbol shape are both driven by the intensity value, using D3’s scaleOrdinal with three fixed colors and symbol types. Implemented as a vanilla HTML/SVG application with d3.csv for data loading, d3.scaleLinear for axes, and a custom scatterPlot function that builds marks via d3.symbol and attaches axis labels dynamically.
