This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG dataset. Each red, semi-transparent circle represents a car, with positions mapped by `d3.scaleLinear` scales, and axes rendered using `d3.axisBottom` and `d3.axisLeft`. The code loads data via `d3.csv`, parses numeric fields, and appends SVG circles and text labels. Interactive video instructions are embedded via an iframe. The visualization uses D3 v5, with styling defined in external CSS for ticks, labels, and the title.
