This scatter plot visualizes the Iris dataset, showing the relationship between two selected attributes for each flower sample. Users can interactively choose which measurements to display on the x- and y-axes via dropdown menus. The chart uses D3 v4 with SVG rendering, employing `d3.scaleBand` for the categorical x-axis and `d3.scaleLinear` for the y-axis. Each point is colored by species using an ordinal scale, with the data loaded from a CSV file.
