This visualization displays a scatter plot of the Iris Dataset, showing relationships between sepal and petal measurements with points colored by species according to a categorical color legend. It uses D3.js with `scaleLinear` for axes, `scaleOrdinal` with `schemeCategory10` for colors, and `selection.join` for data binding. The code loads data from a CSV file and renders circles with labels, employing modular functions for axes and color legend creation.
