An animated scatter plot visualizes traffic accident data from a CSV file, cycling through four quantitative columns—Speed Limit, Number of Casualties, Number of Vehicles, and Accident Severity—as its axes every two seconds. The visualization uses a reusable D3 scatter plot module that dynamically updates the axis domains and circle positions based on the currently selected variables. Rendered as an SVG via D3 6.7.0, the chart employs `scaleLinear`, `axisLeft`, and `axisBottom` utilities to construct axes and scales, with a fixed y-axis origin and a radius of five pixels for each data point.
