This interactive scatter plot visualizes the relationship between weight and various car attributes from the UCI Auto MPG dataset. A dropdown menu allows users to select which attribute (e.g., horsepower, acceleration) appears on the x-axis, while weight remains on the y-axis. The visualization uses d3.scaleLinear for axes, d3.axisBottom and d3.axisLeft for ticks, and d3.csv to load the data. Red semi-transparent circles are rendered as SVG elements, with axis labels and a title updated dynamically.
