This example visualizes the coefficients of a wine quality regression model, showing how each chemical attribute contributes to the target variable. Using D3 v4 loaded via UNPKG, it renders an animated SVG scatterplot where circles represent attributes plotted against their coefficients on a scale from -1 to 1. The code uses `d3.scaleBand` and `d3.scaleLinear` for axes, with `d3.csv` loading data from a local file. Interactive tooltips appear on mouseover, displaying the coefficient value, while each point is styled with a purple fill and white stroke.
