This scatter plot visualizes car data from the UCI Machine Learning Repository’s Auto MPG dataset, with dropdown menus letting users choose which columns map to the X and Y axes. The visualization uses d3.scaleLinear, d3.axisBottom, and d3.axisLeft to render the axes, while d3.transition animates circles moving to their new positions over two seconds. Data is loaded via d3.csv, and the interactive menus are built with native HTML select elements. The SVG rendering includes gridlines and axis labels that update dynamically.
