scatter plot on wine
This interactive scatter plot matrix visualizes the relationships among several chemical properties of red wine, with each cell showing a pairwise comparison of attributes like fixed acidity, volatile acidity, and pH. Color-coded points represent wine quality ratings, and users can brush over a cell to highlight corresponding data points across all other plots, with tooltips revealing exact values on hover. Built with D3 v4, the visualization uses `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.brush` for interactive selection. The data comes from the included `winequality-red.csv` file, rendered as SVG elements within a grid layout.
