This interactive scatter plot uses dropdown menus to let viewers select which data columns to display on the x- and y-axes. The visualization reads from a CSV file containing movie attributes like budget, gross, and IMDb score. The scatterPlot function creates linear scales, axes, and animated circles using d3.scaleLinear, d3.extent, d3.axisLeft, and d3.axisBottom. A dropdownMenu module builds the select elements with d3 data joins. The circles transition over 2 seconds with staggered delays, showing how axis labels and data points update dynamically when menu options change.
