This scatter plot visualizes worldwide export data from 2000 to 2016, comparing values between countries such as China, Japan, and the United States. A drop-down menu allows the user to select which country appears on the x-axis, while the y-axis remains fixed on Japan. The visualization uses D3 v5 APIs including `scaleLinear`, `axisBottom`, and `axisLeft`, rendering circles in SVG. Data is loaded from a CSV file and parsed into numeric values for each country column.
