This interactive scatter plot displays the relationship between various car attributes, such as horsepower and weight, using data from a CSV file. A dropdown menu allows users to select which attribute is plotted on the x-axis. The visualization is built with D3 v5, using SVG for rendering and animated transitions for the circles. The code specifically utilizes D3's `scaleLinear`, `axisBottom`, `axisLeft`, and `csv` to load data and render the chart, with a `dropdownMenu` component driving the dynamic updates.
